MX7582KN
Calibrated 4-Channel 12-Bit ADC

Calibrated 4-Channel 12-Bit ADC
General Description
The MX7582 is a complete, calibrated 4-channel 12-bit
AID converter which maintains true 12-bit performance
over the full operating temperature range without external
adjustments, In addition, each loops conversion in-.
cludes an auto-zegp cycle which reduces zero errors to
typically below 100W.
CHIP SELECT, READ, and WRITE inputs are included tor
easy microprocessor interfacing without additional logic.
2-byte, 12-bit conversion data is provided over an 8-bit
three-state output bus, Either byte may be read first.
Two address bits control the 4-channel input multiplexer.
The MX7582's analog input range is 0V to +5V when
using a +5V reference, All four high-impedance input
channels have excellent matching (typically 0.05LSB).
