July 26, 2012 12-Bit, 555kSPS SAR ADC
The ISL267452 is a 12-bit, 555kSPS sampling SAR-type ADC
featuring excellent linearity over supply and temperature
variations, and is drop-in compatible with the AD7452. The
robust, fully-differential input offers high impedance to
minimize errors due to leakage currents, and the specified
measurement accuracy is maintained with input signals up to
the supply rails. Features The reference accepts inputs from 0.1V to 2.2V for 3V
operation and 0.1V to 3.5V for 5V operation, which provides
design flexibility in a wide variety of applications. The
ISL267452 also features up to 8kV Human Body Model ESD
survivability. 555kHz Sampling Rate The serial digital interface is SPI compatible and is easily
interfaced to all popular FPGAs and microcontrollers. Power
dissipation is 7mW at a sampling rate of 555kSPS, and just
5ВµW between conversions utilizing Auto Power-Down mode
(with a 5V supply), making the ISL267452 an excellent
solution for remote industrial sensors and battery-powered
instruments.
The ISL267452 is available in an 8 LD SOT-23 package, and is
specified for operation over the Industrial temperature range …
