Pin Description

Name

Function

C3

In serial mode, pin is unused. In parallel mode, coarse gain select bit. Pin has internal pulldown

resistor to GND.

(LATI) C2

In serial mode, input latch clock which loads the data from the shift register into the latch.

In parallel mode, coarse gain select bit. Pin has internal pulldown resistor to GND.

(SID) C1

In serial mode, serial data input that contains serial 9 bit data word which controls the gain

setting. In parallel mode, coarse gain select bit. Pin has internal pulldown resistor to GND.

(LATO) C0

In serial mode, output latch clock which loads the 9 bit data word back into the shift register from

the latch. In parallel mode, coarse gain select bit. Pin has internal pulldown resistor to GND.

normal operation. Pin has internal pulldown resistor to GND.

F3

In serial mode, pin is unused. In parallel mode, fine gain select bit. Pin has internal pulldown

resistor to GND.

(SCK) F2

In serial mode, shift register clock which shifts the serial data on SID into the shift register on

rising edges and out on SOD on falling edges. In parallel mode, fine gain select bit. Pin has

internal pulldown resistor to GND.

F1

In serial mode, pin is unused. In parallel mode, fine gain select bit. Pin has internal pulldown

resistor to GND.

GND

Digital ground. 0 volts. All digital inputs and outputs are referenced to this ground.

SER/PAR

Serial or parallel select input. When SER/PAR = 1, device is in serial mode.

(SOD) F0

In serial mode, serial output data which is the output of the shift register. In parallel mode, fine

gain select bit. Pin has internal pulldown resistor to GND.

Analog input.

AGND

Analog ground. 0 volts. Analog input and output are referenced to this ground.

Negative supply. –5 volts ±10%.

Analog output.

Positive supply. +5 volts ±10%.

ATTEN/GAIN

In serial mode, pin is unused. In parallel mode, attenuation/gain select bit. Pin has internal

pulldown resistor to GND.
