TSA1203 Datasheet | STMicroelectronics

Features - Low power consumption: 215 m W@40 Msps - Single supply voltage: 2.5 V - Independent supply for CMOS output stage with 2.5 V/3.3 V capability - SFDR = -75 d Bc @ Fin = 10 MHz - 1GHz analog bandwidth track-and-hold - mon 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 ponents. It is nevertheless possible to use the circuit with external references. The ADC binary word outputs are multiplexed in a mon 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 corner AGND 1 INI 2 AGND 3 INIB 4 AGND 5 IPOL 6 AVCCB 7 AGND 8 INQ 9 AGND 10 INBQ 11 AGND 12 48 47 46 45 44 43 42 41 40 39 38 37 36 D2 35 D3 34 D4 33 D5 32 D6 31 D7 30 D8 29 D9 28 D10 27 D11(MSB) 26 VCCBE 25 GNDBE 13 14 15 16 17 18 19 20 21 22 23 24 GNDBI DVCC DGND SELECT CLK DGND DVCC AVCC AGND INCMQ REFMQ REFPQ Applications - Medical imaging and ultrasound - 3G base station - I/Q signal processing applications - High-speed data acquisition systems - Portable instrumentation December 2006 Rev...
