MX7578KN+
Calibrated 12-Bit ADC
2dlyl] 2dfLli)Cl]2ffyfl]
Calibrated 112-13” A/ID Converter
General Description
The MX7578 is a complete, calibrated 12-bit A/D con-
verter (ADC) which includes a conversion clock. Internal
calibration circuitry maintains true 12-bit performance
over the full operating temperature range without external
adjustments. In addition, each conversion includes an
auto-zero cycle which reduces zero errors to typically
below 100pV.
CHIP SELECT, READ, and WRITE inputs are included for
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 converter busy flags facilitate polling of the
converter's status.
The MX7578's analog input range is 0V to +5V when using
a +5V reference. Refer to Maxim's MAX178 data sheet for
a plug-in upgrade with track/hold and internal reference.
