DESCRIPTION The TSA1401 is a 14-bit, 20MHz sampling frequency Analog to Digital Converter using deep submicron CMOS technology combining high performances with very low power consumption.The TSA1401 is based on a pipeline structure with digital error correction to provide excellent static linearity and dynamic performances. Typically designed for multi-channel applications and high-end imaging equipment, where low consumption is a must, the TSA1401 only dissipates 85mW at 20Msps when using external references, 110mW using internal references. Its power consumption adapts relative to sampling frequency. Differential signals are applied on the inputs for optimum performance. The TSA1401 reaches an SFDR of -90.5dBc and an SNR of 73.1dBc at Fin=10MHz when increasing the input dynamic range to 2.5V by using the voltage reference, TS431 (1.24V). A tri-state capability is available on the output buffers, enabling a Chip Select.The TSA1401 is available in the industrial temperature range of - 40°C to +85°C and in a small 48-lead TQFP package. APPLICATIONS s High-end infra-red imaging s X-Ray medical imaging s High-end CCD cameras s Scanners and digital copiers s Test instrumentation s Wireless communication ORDER CODES PIN CONNECTIONS (top view) PACKAGE Part Number Temperature Range Package Conditioning Marking TSA1401IF -40°C to +85°C TQFP48 Tray SA1401 TSA1401IFT -40°C to +85°C TQFP48 Tape & Reel SA1401 EVAL1401/AB Evaluation board 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 TSA1401 VREFM VREFP VINB AGND AGND AGND VIN AVCC AVCC AGND IPOL INCM D1 D2 D3 D4 D5 D6 D7 D8 D11 D9 D10 D12 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 TSA1401 VREFM VREFP VINB AGND AGND AGND VIN AVCC AVCC AGND IPOL INCM D1 D2 D3 D4 D5 D6 D7 D8 D11 D9 D10 D12 7 x 7 mm TQFP48 TSA1401 14-BIT, 20MSPS, 85mW A/D CONVERTER 1/19 December 2003 |
