DESCRIPTION

1

V++

Positive Supply Voltage: Nominally +15V.

2

GND

Digital Ground: 0V, ground return.

3

STTS

Status Output: HI during integrate and deintegrate until data is latched. LO when analog section

is in auto-zero configuration.

4

POL

Polarity: Three-state output. HI for positive input.

5

OR

Over Range: Three-state output.

LBEN

LOW BYTE ENABLE: If not in handshake mode (see pin 27) when LO (with CE/LD, pin 30)

activates low-order byte outputs, BITS 1-8. When in handshake mode (see pin 27), serves as a

low byte flag output. See Figures 11, 12, 13.

MID BYTE ENABLE: Activates Bits 9-16, see LBEN (pin 22)

HBEN

-14

HIGH BYTE ENABLE: Activates Bits 9-14, POL, OR, see LBEN (pin 22)

24

HBEN

-16

HIGH BYTE ENABLE: Activates POL, OR, see LBEN (pin 22).

CLOCK3

-14

RC oscillator pin: Can be used as clock output.
