1 / 22 page 1/22 s 10-bit, dual-channel A/D converter in deep submicron CMOS technology, 20/40Msps s Single supply voltage: 2.5V Independent supply for CMOS output stage with 2.5V/3.3V capability s ENOB=9.5 @ 20Msps, ENOB=9.2 @ 40Msps, Fin=10MHz s SFDR typically up to 62.5dB @ 40Msps, Fin=10MHz. s 1GHz analog bandwidth Track-and-Hold s Common clocking between channels s Multiplexed outputs DESCRIPTION The TSA1005 belongs to a new generation of high speed, dual-channel Analog to Digital converters, processed in a mainstream 0.25 µm CMOS tech- nology and yielding high performances. The TSA1005 is specifically designed for applica- tions requiring a very low noise floor, high SFDR and good isolation between channels. It is based on a pipeline structure and digital error correction, providing high static linearity at 20/40 Msp, and Fin = 10 MHz. 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 output is multiplexed on a common bus with small number of pins. A tri-state capability is available for the output signals, allowing for chip selection. The input signals of the ADC must be differentially driven. The TSA1005 is supports an extended (0 to +85°C) temperature range, and is available in the small 48-pin TQFP package.
