FUNCTION
Analog input 4.
Analog input 3.
Analog input 2.
Analog input 1.
Mode select input.
MODE = GND: RD mode
MODE = VCC: WR-RD mode
Pin has internal current source
pulldown to GND.
Data output — bit 0 (LSB).
Data output — bit 1.
Data output — bit 2.
Data output — bit 3.
Read input. In RD mode, this pin
initiates a conversion. In WR-RD
mode, this pin latches data into output
latches. See Digital Interface section.
Interrupt output. This output signals
the end of a conversion and indicates
that data is valid on the data outputs.
See Digital Interface section.
Ground.
Negative reference voltage for
A/D converter.
Positive reference voltage for
A/D converter.

FUNCTION
Write input or ready output. In WR-RD
mode, this pin is WR input. In RD
mode, this pin is RDY open drain
output. See Digital Interface section.
Chip select input. This pin must be
held low for the device to perform a
conversion.
Data output — bit 4.
Data output — bit 5.
Data output — bit 6.
Data output — bit 7 (MSB).
Digital address input 1 that selects
analog input channel. See multiplexer
addressing section.
Digital address input 0 that selects
analog input channel. See multiplexer
addressing section.
S/H, T/H mode select. When SH/TH =
VCC, the device is in sample and hold
mode. When SH/TH = GND, the
device is in track and hold mode. Pin
has internal pulldown current source
to GND.
Positive supply. +5 volts ± 5%.
ABSOLUTE MAXIMUM RATINGS
