General Description
The MAX178 is a complete, cahbrated 12-bit A/D con-
verter (ADC) which includes a precision voltage refer-
ence, track-and-hold, and converSIon clock. Internal
calibration circuitry maintains true 12-bit performance
over the full operating temperature range without external
adiust'nentsv In addition, each conversion includes an
auto»zero cycle which reduces zero errors to typically
below 100pV
CHIP SECECT, WU ahd WHITE inputs are included for
easy microprocessor interfacing without additional logic,
2-byte, 12-bit conversmn data is provided over an 8-bit
three-state output bus. Either byte may be read first.
Features
. Continqous Transparent Calibration of Offset
and Gain
. True 12-Bit Performance without Adjustments
. T/H Front End and Internal Reference
. DC and Dynamically Specified
. Zero Error Typically <100pV
. Standard Microprocessor Interface
. 24-Pin DIP and Wide SO Packages
