1 / 30 page  December 2006 Rev 4 1/30 30 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 D5 D6 D7 D8 D9 D10 D11(MSB) AVCCB index corner 1 2 3 4 5 6 7 8 9 10 11 32 31 30 29 28 27 26 13 14 15 16 17 18 19 20 21 22 47 25 33 12 23 24 35 34 36 48 44 43 42 41 40 39 38 37 46 45 TSA1203 VCCBE GNDBE AGND INI AGND AGND IPOL AGND AGND INBQ INIB AGND INQ D2 D3 D4 7x7mm TQFP48 www.st.com Obsolete Product(s) - Obsolete Product(s) |
