ISL267450
ISL267450 is 1MSPS SAR ADCs manufactured by Renesas.
12-Bit, 1MSPS SAR ADCs
The ISL267450 is a 12-bit, 1MSPS sampling SAR-type ADC with a differential input span of 2- VREF volts. The ISL267450 Features excellent linearity over supply and temperature variations and is drop-in patible 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 patible and is easily interfaced to popular FPGAs and microcontrollers. Power dissipation is 9.0m W 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).
