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.
