DATASHEET
ISL267450
12-Bit, 1MSPS SAR ADCs
The ISL267450 is a 12-bit, 1MSPS sampling SAR-type ADC
with a differential input span of 2*V
REF
volts. The ISL267450
features excellent linearity over supply and temperature
variations and is drop-in compatible with the AD7450. The
device can operate from a supply voltage of either 5V or 3V
and maintain measurement accuracy with input signals up to
the supply rails.
The serial digital interface is SPI compatible and is easily
interfaced to popular FPGAs and microcontrollers. Power
dissipation is 9.0mW at a sampling rate of 1MSPS, and just
5µW between conversions utilizing Auto Power-Down mode
(with a 3V supply).
The ISL267450 is available in 8 Ld SOIC or MSOP packages,
and are specified for operation over the Industrial temperature
range (–40°C to +85°C).
