Description

IC 8BIT ADC SMD 9281 SOIC28

The AD9281 is a complete dual channel, 28 MSPS, 8-bit CMOS ADC. The AD9281 is optimized specifically for applica- tions where close matching between two ADCs is required (e.g., I/Q channels in communications applications). The 28 MHz sampling rate and wide input bandwidth will cover both narrow- band and spread-spectrum channels. The AD9281 integrates two 8-bit, 28 MSPS ADCs, two input buffer amplifiers, an internal voltage reference and multiplexed digital output buffers. Each ADC incorporates a simultaneous sampling sample-and- hold amplifier at its input. The analog inputs are buffered; no external input buffer op amp will be required in most applica- tions. The ADCs are implemented using a multistage pipeline architecture that offers accurate performance and guarantees no missing codes. The outputs of the ADCs are ported to a multi- plexed digital output buffer. The AD9281 is manufactured on an advanced low cost CMOS process, operates from a single supply from 2.7 V to 5.5 V, and consumes 225 mW of power (on 3 V supply). The AD9281 input structure accepts either single-ended or differential signals, providing excellent dynamic performance up to and beyond 14 MHz Nyquist input frequencies.
