Product Details

The AD9203 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter with an on-chip voltage reference. It uses a multistage differential pipeline architecture at 40 MSPS data rate and guarantees no missing codes over the full operating temperature range. Its input range may be adjusted between 1 V and 2 VP-P.

The ADC has an on-board programmable reference. An external reference can also be chosen to suit the DC accuracy and temperature drift requirements of an application. An external resistor can be used to reduce power consumption when operating at lower sampling rates.

A single clock input is used to control all internal conversion cycles. The digital output data is presented in straight binary or two's complement output format. An out-of-range signal (OTR) indicates an over-flow condition that can be used with the most significant bit to determine over-flow or under-flow. The AD9203 can operate with a supply range from 2.7 V to 3.6 V, attractive for low power operation in high-speed portable applications.

Fabricated on an advanced CMOS process, the AD9203 is available in a 28-pin thin shrink small outline package (28 TSSOP) specified over the industrial temperature range (−40°C to +85°C).
