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 = 10 MHz
■ 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 = 10 MHz.
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.
