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 initial-

ized. 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 neces-

sary, fabricate the gain resistor from a precision metal-ﬁlm type in series

with a low value trim resistor or potentiometer. The total resistor tempera-

ture coefﬁcient must be no greater than 10ppm/°C.

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).

*Same as HDAS-16

Caution: Pins 49 and 50 do not have overvoltage protection; therefore, protected multiplexers,

such as MPS’s MX-1606 and MX-808 are recommended. See the General Operation description.

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. Change the output of the precision voltage source to the value shown in

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.

Optional gain selection point. Factory adjusted for G = 1

when left open.

RDELAY

Optional acquisition time adjustment when connected

to +5V. Factory adjusted for 9μs. Must be connected to

+5V either directly or through a resistor.

HDAS-16, HDAS-8

12-Bit, 50kHz, Complete Data Acquisition Systems

The acquisition time is the amount of time the multiplexer, instrumenta-

tion 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 con-

necting 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 resis-

tors 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 address-

ing 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,

Random Addressing

tents of the address counter to be incremented by one, followed by an

A/D conversion in 9 microseconds.

Set pin 19 (LOAD) to logic 0. The next falling edge of STROBE will load the MUX

CHANNEL ADDRESS present on pin 13 to pin 16. Digital address inputs must be

stable 20ns before andafter falling edge of the STROBE pulse.

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.

Free Running Sequential Addressing

Set pin 19 (LOAD) and pin 20 (CLEAR) to logic 1 or leave open. Connect pin 7

(EOC) to pin 8 (STROBE). The fallingedge of EOC will increment channel

address. This means thatwhen the EOC is low, the digital output data is valid

for theprevious channel (CHn – 1) rather than the channel indicated on

MUX ADDRESS OUTPUT. The HDAS will continually scan all channels.

The value of Ri for a speciﬁc voltage protection range (Vp) can be calculated

by the following formula:

Example: CH4 has been addressed and a conversion takes place. The EOC

goes low. That channel’s (CH4’s) data becomes valid, but MUX ADDRESS

OUTPUT is now CH5.

Vp = (Rsignal + Ri + R^ON) (10mA)where RON = 2k

NOTE: Increased input series resistance will increase multiplexer settling

time signiﬁcantly.

Triggered Sequential Addressing

Set pin 19 (LOAD) and pin 20 (CLEAR) to logic 1 or leaveopen. Apply a falling

edge trigger pulse to pin 8 (STROBE).This negative transition causes the con-
