ISL267450A 1MSPS SAR ADC

ISL267440, ISL267450A PIN NAME PIN NUMBER DESCRIPTION VDD 8 Supply voltage, +2.7V to 5.25V. SCLK 7 Serial clock input. Controls digital I/O timing and clocks the conversion. SDATA 6 Digital conversion output. CS 5 Chip select input. Generally controls the start of a conversion though not a.

ISL267440, ISL267450A 10-Bit and 12-Bit, 1MSPS SAR ADCs The ISL267440 and ISL267450A are 10-bit and 12-bit, 1MSPS sampling SAR-type ADCs featuring excellent linearity over supply and temperature variations. These devices are drop-in compatible with the AD7440 and AD7450A. 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. The reference accepts inputs.
