Description

The CLC952 is a complete monolithic 12-bit 41MSPS analog-todigitaconverter system. Fabricated from a 0.8mm BiCMO 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 communications receivers and features a 72dBc spurious-free dynamic range (SFDR) and 64dB signal-to-noise ratio (SNR).

The CLC952 operates from a standard ±5V power supply and features excellent noise isolation with its >60dB power-supply rejection ratio (PSRR). All digital control functions and output registers are TTL compatible. The CLC952AC operates over the commercial 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 compliance with guaranteed specifications.
