TSA1203

Dual-channel 12-bit 40Msps 215mW A/D converter

Features

■ Low power consumption: 215 mW@40 Msps

■ Single supply voltage: 2.5 V

■ Independent supply for CMOS output stage

with 2.5 V/3.3 V capability

■ SFDR = -75 dBc @ Fin =10MHz

■ 1GHz analog bandwidth track-and-hold

■ Common clocking between channels

■ Dual simultaneous sample and hold inputs

■ Multiplexed binary word outputs

■ Built-in reference voltage with external bias

capability

Description

The TSA1203 is a new generation high-speed,

dual-channel analog-to-digital converter

implemented in a mainstream 0.25 µm CMOS

technology that offers high performance and very

low power consumption.

The TSA1203 is specifically designed for

applications requiring a very low noise floor, high

SFDR and good insulation between channels. It is

based on a pipeline structure and digital error

correction to provide high static linearity at

FS = 40 Msps, and Fin =10MHz.

Each channel has an integrated voltage reference

to simplify the design and minimize external

components. It is nevertheless possible to use the

circuit with external references.

The ADC binary word outputs are multiplexed in a

common bus with a small number of pins.

A tri-state capability is available for the outputs,

allowing chip selection. The inputs of the ADC

must be differentially driven.

The TSA1203 is available in extended

temperature range (-40° C to +85° C), in a small

48-pin TQFP package.

Applications

■ Medical imaging and ultrasound

■ 3G base station

■ I/Q signal processing applications

■ High-speed data acquisition systems

■ Portable instrumentation
