If the power is off, the maximum safe input (no damage) is ±20V. The gain equation error is guaranteed before external trimming and applies at gains less than 50. This error increases at gains over 50. Adjustable to zero. STROBE pulse width must be less than EOC period to achieve maximum throughput rate. TECHNICAL NOTES 1. Input channels are protected to 20 Volts beyond the powersupplies. All digital output pins have one second short-circuit protection. 2. To retain high system throughput rates while digitizing low-level signals, apply external high-gain amplifiers foreach channel. MPS’s AM-551 is suggested for such amplifier-per-channel applications. 3. The HDAS devices have self-starting circuits for free-running sequential operation. If, however, in a power-upcondition the supply voltage slew rate is less than 3V per microsecond, the free running state might not be initialized. Apply a negative pulse to the STROBE, to eliminate this condition. 4. For unipolar operation, connect BIPOLAR INPUT (pin 38) to S/H OUT (pin 39). For bipolar operation, connect BIPOLAR INPUT (pin 38) to +10V REFERENCE OUT (pin 40). 5. RDELAY may be a standard value 5% carbon composition or film-type resistor. 6. RGAIN must be very accurate with low temperature coefficients. If necessary, fabricate the gain resistor from a precision metal-film type in series with a low value trim resistor or potentiometer. The total resistor temperature coefficient must be no greater than ±10ppm/°C. 7. ANALOG SIGNAL COMMON, POWER COMMON and DIGITAL COMMON are connected internally. For optimal performance, tie all ground pins (17, 41, 42, 45, 46) directly to a large analog ground plane beneath the package. 8. For HDAS-16, tie pin 50 to a “signal source common” if possible. Otherwise tie pin 50 to pin 41 (ANA SIG COM).

Calibration Procedures 1. Offset and gain adjustments are made by connecting two 20k trim potentiometers as shown in Figure 2. 2. Connect a precision voltage source to pin 4 (CH0 IN). If the HDAS-8 is used, connect pin 58 (CH0 LOW IN) to analog ground. Ground pin 20 (CLEAR) and momentarily short pin8 (STROBE). Trigger the A/D by connecting pin 7 (EOC) to pin 8 (STROBE). Select proper value for RGAIN and RDELAY by referring to Table 3. 3. Adjust the precision voltage source to the value shown in Table 2 for the unipolar zero adjustment (ZERO + 1/2LSB)or the bipolar offset adjustment (–FS + 1/2LSB). Adjust the offset trim potentiometer so that the output code flickers equally between 0000 0000 0000 and 0000 0000 0001. 4.

External Adjustment GENERAL OPERATION The HDAS devices accept either 16 single-ended or 8 differential input signals. For single-ended circuits, the AMP INLOW (pin 50) input to the instrumentation amplifier must terminate at ANALOG SIGNAL COMMON (pin 41). For differential circuits, both the HIGH and LOW signal inputs must terminate externally for each channel. Tie unused channels to the ANALOG SIGNAL COMMON (pin 41). To obtain additional channels, connect external multiplexers to the AMP IN HIGH (pin 49) and AMP IN LOW (pin 50). Using this scheme, the HDAS-16 can provide 32 single-ended expansion channels while the HDAS-8 can provide up to 16 differential expansion channels. MPS’s MX Series multiplexers are recommended. Technical enquiries email: [email protected], tel: +1 508 339 3000 MDC_HDAS-16/8.B01 Page 4 of 7 HDAS-16, HDAS-8 The acquisition time is the amount of time the multiplexer, instrumentation amplifier, and sample/hold require to settle within a specified range of accuracy after STROBE (pin 8)goes low. The acquisition time period can be observed by measuring how long EOC is low after the falling edge of STROBE (see Figure 4). For higher gains, increase the acquisition time. Do this by connecting a resistor from RDELAY (pin 6) to +5V (pin 18). An external resistor, RGAIN, can be added to increase the gain value. The gain is equal to 1 without an RGAIN resistor. Table 3 refers to the appropriate RDELAY and RGAIN resistors required for various gains. driving the EOC output high.The HDAS devices can be configured for either bipolar or unipolar operation (see Table 2). The conversion is complete within a maximum of 10 microseconds. The EOC now returns low, the data is valid and sent to the three-state output buffers.The sample/hold amplifier is now ready to acquire new data.The next falling edge of the STROBE pulse repeats the process for the next conversion. Multiplexer Addressing The HDAS devices can be configured in either random orsequential addressing modes. Refer to Table 5 and the subsequent descriptions. The number of channels sequentially addressed can be truncated using the MUX ADDRESS OUT(pins 9, 10, 11 and 12) and appropriate decoding circuitry forthe highest channel desired. The decoding circuit can drive the CLEAR (pin 20) function low to reset the addressing to channel 0. The HDAS devices enter the hold mode and are ready for conversion as soon as the one-shot (controling acquisition time) times out. An internal clock is gated ON, and a start-convert pulse is sent to the 12-bit A/D converter, Table 3.

Input Voltage Protection As shown in Figure 3, the multiplexer has reversed biased diodes which protect the input channels from being damaged by overvoltage signals. The HDAS input channels areprotected up to 20V beyond the supplies and can be increasedby adding series resistors (Ri) to each channel. The input resistor must limit the current flowing through the protection diodes to 10mA. The value of Ri for a specific voltage protection range (Vp) can be calculated by the following formula: Vp = (Rsignal + Ri + RON) (10mA)where RON = 2k NOTE: Increased input series resistance will increase multiplexer settling time significantly.
