AD7767BRUZ-2-RL7 Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD7767/AD7767-1/AD7767-2 are high performance 24-bit oversampled SAR analog-to-digital converters (ADC). The AD7767/AD7767-1/AD7767-2 combine the benefits of a large dynamic range and input bandwidth, consuming 15 mW, 10.5 mW, and 8.5 mW power, respectively, all contained in a 16-lead TSSOP package.
