STMicroelectronics TSA1203
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.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
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. 7x7mm TQFP48 D1 D0(LSB) VCCBE GNDBE VCCBI VCCLCKBDI OEB AVCC AVCC INCMI REFMI REFPI index...
