Data Sheet 2.7 V to 5.5 V, <100 μA, 8-/10-/12-Bit nanoDAC, SPI Interface in LFCSP and SC70 AD5601/AD5611/AD5621 FEATURES APPLICATIONS Voltage level setting Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators GENERAL DESCRIPTION The AD5601/AD5611/AD5621, members of the nanoDAC® family, are single, 8-/10-/12-bit, buffered voltage output DACs that operate from a single 2.7 V to 5.5 V supply, consuming typically 75 µA at 5 V. The parts come in tiny LFCSP and SC70 packages. Their on-chip precision output amplifier allows railto-rail output swing to be achieved. The AD5601/AD5611/ AD5621 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards. The reference for the AD5601/AD5611/AD5621 is derived from the power supply inputs and, therefore, gives the widest dynamic output range. The parts incorporate a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write to the device takes place. The AD5601/AD5611/AD5621 contain a power-down feature that reduces current consumption to typically 0.2 µA at 3 V.

See Figure 5 to Figure 7 for plots of typical INL vs. code. Differential Nonlinearity Differential nonlinearity (DNL) is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ±1 LSB maximum ensures monotonicity. This DAC is guaranteed monotonic by design. See Figure 11 to Figure 13 for plots of typical DNL vs. code. Zero-Code Error Zero-code error is a measure of the output error when zero code (0x0000) is loaded to the DAC register. Ideally, the output should be 0 V. The zero-code error is always positive in the AD5601/AD5611/AD5621 because the output of the DAC cannot go below 0 V. Zero-code error is due to a combination of the offset errors in the DAC and output amplifier. Zero-code error is expressed in mV. See Figure 28 for a plot of zero-code error vs. temperature. Full-Scale Error Full-scale error is a measure of the output error when full-scale code (0xFFFF) is loaded to the DAC register. Ideally, the output should be VDD − 1 LSB. Full-scale error is expressed in mV. See Figure 28 for a plot of full-scale error vs. temperature. Total Unadjusted Error Total unadjusted error (TUE) is a measure of the output error, taking all the various errors into account. See Figure 8 to Figure 10 for plots of typical TUE vs. code. Zero-Code Error Drift Zero-code error drift is a measure of the change in zero-code error with a change in temperature. It is expressed in µV/°C. Gain Temperature Coefficient Gain temperature coefficient is a measure of the change in gain error with changes in temperature. It is expressed in (ppm of full-scale range)/°C. Digital-to-Analog Glitch Impulse Digital-to-analog glitch impulse is the impulse injected into the analog output when the input code in the DAC register changes state. It is normally specified as the area of the glitch in nV-s and is measured when the digital input code is changed by 1 LSB at the major carry transition (0x2000 to 0x1FFF). See Figure 19. Digital Feedthrough Digital feedthrough is a measure of the impulse injected into the analog output of the DAC from the digital inputs of the DAC, but is measured when the DAC output is not updated. It is specified in nV-s and is measured with a full-scale code change on the data bus—from all 0s to all 1s and vice versa. Gain Error Gain error is a measure of the span error of the DAC. It is the deviation in slope of the DAC transfer characteristic from the ideal, expressed as a percent of the full-scale range. Rev. F | Page 13 of 24 AD5601/AD5611/AD5621 Data Sheet THEORY OF OPERATION DAC SECTION OUTPUT AMPLIFIER The AD5601/AD5611/AD5621 DACs are fabricated on a CMOS process. The architecture consists of a string DAC followed by an output buffer amplifier. Figure 39 is a block diagram of the DAC architecture. The output buffer amplifier is capable of generating rail-to-rail voltages on its output, giving an output range of 0 V to VDD. It is capable of driving a load of 2 kΩ in parallel with 1000 pF to GND. The source and sink capabilities of the output amplifier are shown in Figure 25. The slew rate is 0.5 V/µs, with a halfscale settling time of 8 µs with the output loaded. VDD REF (+) SERIAL INTERFACE RESISTOR NETWORK DAC REGISTER REF (–) VOUT 06853-038 OUTPUT AMPLIFIER GND Figure 39. DAC Architecture Because the input coding to the DAC is straight binary, the ideal output voltage is given by D VOUT = VDD × n 2 where: D is the decimal equivalent of the binary code that is loaded to the DAC register. n is the bit resolution of the DAC. RESISTOR STRING The resistor string structure is shown in Figure 40. It is simply a string of resistors, each of Value R. The code loaded to the DAC register determines at which node on the string the voltage is tapped off to be fed into the output amplifier. The voltage is tapped off by closing one of the switches connecting the string to the amplifier. Because it is a string of resistors, it is guaranteed monotonic. R R TO OUTPUT AMPLIFIER R The AD5601/AD5611/AD5621 have a 3-wire serial interface (SYNC, SCLK, and SDIN) that is compatible with SPI, QSPI, and MICROWIRE interface standards as well as most DSPs. See Figure 2 for a timing diagram of a typical write sequence. The write sequence begins by bringing the SYNC line low. Data from the SDIN line is clocked into the 16-bit shift register on the falling edge of SCLK. The serial clock frequency can be as high as 30 MHz, making the AD5601/AD5611/AD5621 compatible with high speed DSPs. On the 16th falling clock edge, the last data bit is clocked in and the programmed function is executed (a change in DAC register contents and/or a change in the mode of operation). At this stage, the SYNC line may be kept low or brought high. In either case, it must be brought high for a minimum of 33 ns before the next write sequence so that a falling edge of SYNC can initiate the next write sequence. Because the SYNC buffer draws more current when VIN = 1.8 V than it does when VIN = 0.8 V, SYNC should be idled low between write sequences for even lower power operation of the part, as mentioned previously. However, it must be brought high again just before the next write sequence. INPUT SHIFT REGISTER The input shift register is 16 bits wide (see Figure 41). The first two bits are control bits, which control the operating mode of the part (normal mode or any one of three power-down modes). For a complete description of the various modes, see the Power-Down Modes section. For the AD5621, the next 12 bits are the data bits, which are transferred to the DAC register on the 16th falling edge of SCLK. The information in the last two bits is ignored by the AD5621. See Figure 42 and Figure 43 for the AD5611 and AD5601 input shift register map. SYNC INTERRUPT R 06853-039 R In a normal write sequence, the SYNC line is kept low for at least 16 falling edges of SCLK and the DAC is updated on the 16th falling edge. However, if SYNC is brought high before the 16th falling edge, this acts as an interrupt to the write sequence. The shift register is reset and the write sequence is seen as invalid. Neither an update of the DAC register contents nor a change in the operating mode occurs (see Figure 44). Figure 40. Resistor String Structure Rev.

The DAC register is filled with 0s and the output voltage is 0 V. It remains there until a valid write sequence is made to the DAC. This is useful in applications in which it is important to know the state of the DAC output while it is in the process of powering up. AD5601/AD5611/AD5621 to ADSP-2101 Interface The AD5601/AD5611/AD5621 have four separate modes of operation. These modes are software-programmable by setting two bits (DB15 and DB14) in the control register. Table 6 shows how the state of the bits corresponds to the operating mode of the device.

Figure 45 shows the output stage. Figure 47 shows a serial interface between the AD5601/AD5611/ AD5621 and the 68HC11/68L11 microcontroller. SCK of the 68HC11/68L11 drives the SCLK of the AD5601/AD5611/ AD5621, while the MOSI output drives the serial data line of the DAC. The SYNC signal is derived from a port line (PC7). The setup conditions for correct operation of this interface are as follows: the 68HC11/68L11 should be configured so that the CPOL bit is 0 and the CPHA bit is 1. When data is being transmitted to the DAC, the SYNC line is taken low (PC7). When the 68HC11/68L11 are configured as indicated, data appearing on the MOSI output is valid on the falling edge of SCK. Serial data from the 68HC11/68L11 is transmitted in 8-bit bytes with only eight falling clock edges occurring in the transmit cycle. Data is transmitted MSB first. To load data to the AD5601/AD5611/ AD5621, PC7 is left low after the first eight bits are transferred and a second serial write operation is performed to the DAC. PC7 is taken high at the end of this procedure. VOUT RESISTOR NETWORK 06853-044 68HC11/ 68L11* POWER-DOWN CIRCUITRY SCLK Figure 46. AD5601/AD5611/AD5621 to ADSP-2101 Interface Not only does the supply current fall, but the output stage is also internally switched from the output of the amplifier to a resistor network of known values. This has the advantage that the output impedance of the part is known while the part is in power-down mode. AMPLIFIER SYNC DT *ADDITIONAL PINS OMITTED FOR CLARITY When both bits are set to 0, the part has normal power consumption of 100 µA maximum at 5 V.

However, the contents of the DAC register are unaffected when in power-down. The time to exit powerdown is typically 13 µs for VDD = 5 V and 16 µs for VDD = 3 V. See Figure 21 for a plot. Rev.

The ADSP-2101 should be set up to operate in SPORT transmit alternate framing mode. The ADSP-2101 SPORT is programmed through the SPORT control register and should be configured as follows: internal clock operation, active low framing, and 16-bit word length. Transmission is initiated by writing a word to the Tx register after the SPORT is enabled. Data Sheet AD5601/AD5611/AD5621 Figure 48 shows a serial interface between the AD5601/AD5611/ AD5621 and the Blackfin ADSP-BF53x microprocessor. The ADSP-BF53x processor family incorporates two dual-channel synchronous serial ports, SPORT1 and SPORT0, for serial and multiprocessor communications. Using SPORT0 to connect to the AD5601/AD5611/AD5621, the setup for the interface is as follows: DT0PRI drives the SDIN pin of the AD5601/AD5611/ AD5621, while TSCLK0 drives the SCLK of the part.

The setup for the interface is as follows: TxD of the 80C51/80L51 drives SCLK of the AD5601/AD5611/AD5621, while RxD drives the serial data line of the part. The SYNC signal is again derived from a bit programmable pin on the port. In this case, Port Line P3.3 is used. When data is to be transmitted to the AD5601/AD5611/AD5621, P3.3 is taken low. The 80C51/80L51 transmit data only in 8-bit bytes; therefore, only eight falling clock edges occur in the transmit cycle. To load data to the DAC, P3.3 is left low after the first eight bits are transmitted, Figure 50 shows an interface between the AD5601/AD5611/ AD5621 and any MICROWIRE-compatible device. Serial data is shifted out on the falling edge of the serial clock and is clocked into the AD5601/AD5611/AD5621 on the rising edge of the SK.

Because of this, the choice of reference depends on the application requirements. For applications with space-saving requirements, the ADR02 is recommended. It is available in an SC70 package and has excellent drift at 9 ppm/°C (3 ppm/°C in the R-8 package) and provides very good noise performance at 3.4 µV p-p in the 0.1 Hz to 10 Hz range. The AD5601/AD5611/AD5621 have been designed for singlesupply operation, but a bipolar output range is also possible using the circuit shown in Figure 52. The circuit in Figure 52 gives an output voltage range of ±5 V.

Rev. F | Page 18 of 24 06853-051 Because the supply current required by the AD5601/AD5611/ AD5621 is extremely low, the parts are ideal for low supply applications. The ADR395 voltage reference is recommended in this case. It requires less than 100 µA of quiescent current and can, therefore, drive multiple DACs in one system, if required. It also provides very good noise performance at 8 µV p-p in the 0.1 Hz to 10 Hz range. R2 = 10kΩ Data Sheet AD5601/AD5611/AD5621 USING THE AD5601/AD5611/AD5621 WITH A GALVANICALLY ISOLATED INTERFACE POWER SUPPLY BYPASSING AND GROUNDING In process control applications in industrial environments, it is often necessary to use a galvanically isolated interface to protect and isolate the controlling circuitry from any hazardous common-mode voltages that might occur in the area where the DAC is functioning. iCoupler® provides isolation in excess of 2.5 kV. Because the AD5601/AD5611/AD5621 use a 3-wire serial logic interface, the ADuM1300 3-channel digital isolator provides the required isolation (see Figure 53). The power supply to the part also needs to be isolated, which is done by using a transformer. On the DAC side of the transformer, a 5 V regulator provides the 5 V supply required for the AD5601/ AD5611/AD5621. 5V REGULATOR POWER 10µF 0.1µF VDD VOA VIA SCLK ADuM1300 SDI VIB VOB SYNC DATA VIC VOC SDIN AD5601/ AD5611/ AD5621 GND VOUT 06853-052 SCLK Figure 53. AD5601/AD5611/AD5621 with a Galvanically Isolated Interface When accuracy is important in a circuit, it is helpful to carefully consider the power supply and ground return layout on the board. The PCB containing the AD5601/AD5611/AD5621 should have separate analog and digital sections, each having its own area of the board. If the AD5601/AD5611/AD5621 are in a system where other devices require an AGND-to-DGND connection, the connection should be made at one point only. This ground point should be as close as possible to the AD5601/AD5611/AD5621. The power supply to the AD5601/AD5611/AD5621 should be bypassed with 10 µF and 0.1 µF capacitors. The capacitors should be physically as close as possible to the device, with the 0.1 µF capacitor ideally right up against the device. The 10 µF capacitors are the tantalum bead type. It is important that the 0.1 µF capacitor have low effective series resistance (ESR) and effective series inductance (ESI), such as in common ceramic types of capacitors. This 0.1 µF capacitor provides a low impedance path to ground for high frequencies caused by transient currents due to internal logic switching. The power supply line itself should have as large a trace as possible to provide a low impedance path and reduce glitch effects on the supply line. Clocks and other fast switching digital signals should be shielded from other parts of the board by digital ground. Avoid crossover of digital and analog signals, if possible. When traces cross on opposite sides of the board, ensure that they run at right angles to each other to reduce feedthrough effects on the board. The best board layout technique is the microstrip technique, where the component side of the board is dedicated to the ground plane only and the signal traces are placed on the solder side. However, this is not always possible with a two-layer board. Rev.
