description
The TLC5628C and TLC5628I are octal 8-bit voltage output digital-to-analog converters (DACs) with buffered
reference inputs (high impedance). The DACs produce an output voltage that ranges between either one or two
times the reference voltages and GND and are monotonic. The device is simple to use, running from a single
supply of 5 V. A power-on reset function is incorporated to ensure repeatable start-up conditions.
Digital control of the TLC5628C and TLC5628I are over a simple three-wire serial bus that is CMOS compatible
and easily interfaced to all popular microprocessor and microcontroller devices. The 12-bit command word
comprises eight bits of data, three DAC select bits, and a range bit, the latter allowing selection between the
times 1 or times 2 output range. The DAC registers are double buffered, allowing a complete set of new values
to be written to the device, then all DAC outputs are updated simultaneously through control of LDAC. The digital
inputs feature Schmitt triggers for high-noise immunity.
The 16-terminal small-outline (D) package allows digital control of analog functions in space-critical
applications. The TLC5628C is characterized for operation from 0°C to 70°C. The TLC5628I is characterized
for operation from – 40°C to 85°C. The TLC5628C and TLC5628I do not require external trimming.

detailed description
The TLC5628 is implemented using eight resistor-string DACs. The core of each DAC is a single resistor with
256 taps, corresponding to the 256 possible codes listed in Table 1. One end of each resistor string is connected
to GND and the other end is fed from the output of the reference input buffer. Monotonicity is maintained by use
of the resistor strings. Linearity depends upon the matching of the resistor segments and upon the performance
of the output buffer. Since the inputs are buffered, the DACs always present a high-impedance load to the
reference sources. There are two input reference terminals; REF1 is used for DACA through DACD and REF2
is used by DACE through DACH.
Each DAC output is buffered by a configurable-gain output amplifier, that can be programmed to times 1 or times
2 gain.
On power up, the DACs are reset to CODE 0.
Each output voltage is given by:

(1

where CODE is in the range 0 to 255 and the range (RNG) bit is a 0 or 1 within the serial control word.

data interface
With LOAD high, data is clocked into the DATA terminal on each falling edge of CLK. Once all data bits have
been clocked in, LOAD is pulsed low to transfer the data from the serial input register to the selected DAC as
shown in Figure 1. When LDAC is low, the selected DAC output voltage is updated when LOAD goes low. When
LDAC is high during serial programming, the new value is stored within the device and can be transferred to
the DAC output at a later time by pulsing LDAC low as shown in Figure 2. Data is entered most significant bit
(MSB) first. Data transfers using two 8-clock cycle periods are shown in Figures 3 and 4.

Table 2 lists the A2, A1, and A0 bits and the selection of the updated DACs. The RNG bit controls the DAC output
range. When RNG = low, the output range is between the applied reference voltage and GND, and when
RNG = high, the range is between twice the applied reference voltage and GND.

linearity, offset, and gain error using single-end supplies
When an amplifier is operated from a single supply, the voltage offset can still be either positive or negative. With
a positive offset voltage, the output voltage changes on the first code change. With a negative offset the output
voltage may not change with the first code depending on the magnitude of the offset voltage.
The output amplifier, therefore, attempts to drive the output to a negative voltage. However, because the most
negative supply rail is ground, the output cannot drive below ground.
The output voltage remains at 0 V until the input code value produces a sufficient output voltage to overcome
the inherent negative offset voltage, resulting in the transfer function shown in Figure 5.

Voltage
0V
DAC Code

Offset
Figure 5. Effect of Negative Offset (Single Supply)
This offset error, not the linearity error, produces the breakpoint. The transfer function would have followed the
dotted line if the output buffer could drive below ground.
For a DAC, linearity is measured between the zero-input code (all inputs are 0) and the full-scale code (all inputs
are 1) after offset and full scale are adjusted out or accounted for in some way. However, single-supply operation
does not allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the
linearity in the unipolar mode is measured between full-scale code and the lowest code that produces a positive
output voltage.
The code is calculated from the maximum specification for the negative offset voltage.

NOTES: 1. Integral nonlinearity (INL) is the maximum deviation of the output from the line between zero and full scale (excluding the effects
of zero code and full-scale errors).
2. Differential nonlinearity (DNL) is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes.
Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code.
3. Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
4. Zero-scale-error temperature coefficient is given by: ZSETC = [ZSE(Tmax) – ZSE(Tmin)]/Vref × 106/(Tmax – Tmin).
5. Full-scale error is the deviation from the ideal full-scale output (Vref – 1 LSB) with an output load of 10 kΩ.
6. Full-scale error temperature coefficient is given by: FSETC = [FSE(Tmax) – FSE (Tmin)]/Vref × 106/(Tmax – Tmin).
7. Zero-scale-error rejection ratio (ZSE RR) is measured by varying the VDD from 4.5 V to 5.5 V dc and measuring the proportion of
this signal imposed on the zero-code output voltage.
8. Full-scale-error rejection ratio (FSE RR) is measured by varying the VDD from 4.5 V to 5.5 V dc and measuring the proportion of
this signal imposed on the full-scale output voltage.

11. Channel-to-channel isolation is measured by setting the input code of one DAC to FF hex and the code of all other DACs to 00 hex
with Vref input = 1 V dc + 1 Vpp at 10 kHz.
