CLC952
CLC952 is 41MSPS Monolithic A/D Converter manufactured by National Semiconductor.
Description
The CLC952 is a plete monolithic 12-bit 41MSPS analog-todigital converter system. Fabricated from a 0.8µm Bi CMOS process, the CLC952’s on-chip features include a very linear wideband track-and-hold, bandgap voltage reference and a proprietary 12-bit multi-stage quantizer. The CLC952 has been designed for wideband digital munications receivers and features a 72d Bc spurious-free dynamic range (SFDR) and 64d B signal-to-noise ratio (SNR). The CLC952 operates from a standard ±5V power supply and features excellent noise isolation with its >60d B power-supply rejection ratio (PSRR). All digital control functions and output registers are TTL patible. The CLC952AC operates over the mercial temperature range (0°C to 70°C), and the CLC952AJ operates over the industrial temperature range (-40°C to 85°C) version. The CLC952 is available in a 28-pin SSOP that provides an extremely small footprint for reduced board space. National Semiconductor thoroughly tests each part to verify full pliance with guaranteed specifications.
