1 / 20 page  1/20 s Low power consumption: 230mW@40Msps s Single supply voltage: 2.5V Independent supply for CMOS output stage with 2.5V/3.3V capability s SFDR= -68.3 dBc @ Fin=10MHz s 1GHz analog bandwidth Track-and-Hold s Common clocking between channels s Dual simultaneous Sample and Hold inputs s Multiplexed outputs s Built-in reference voltage with external bias capability DESCRIPTION The TSA1203 is a new generation of high speed, dual-channel Analog to Digital converter pro- cessed in a mainstream 0.25µm CMOS technolo- gy yielding high performances and very low power consumption. The TSA1203 is specifically designed for applica- tions requiring very low noise floor, high SFDR and good isolation between channels. It is based on a pipeline structure and digital error correction to provide high static linearity at Fs=40Msps, and Fin=10MHz. For each channel, a voltage reference is integrat- ed to simplify the design and minimize external components. It is nevertheless possible to use the circuit with external references. Each ADC outputs are multiplexed in a common bus with small number of pins. A tri-state capabili- ty is available for the outputs, allowing chip selec- tion. The inputs of the ADC must be differentially driven. The TSA1203 is available in extended (0 to +85°C) temperature range, in a small 48 pins TQFP package.
