CLC952 General 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.
CLC952 Maximum Ratings
positive supply voltage (VCC) -0.5V to +6V
negative supply voltage (VEE) +0.5V to -6V
differential voltage between any two grounds <200mV
analog input voltage range VEE to VCC
digital input voltage range -0.5V to +VCC
output short circuit duration (one-pin to ground) infinite
junction temperature 175°C
storage temperature range -65°C to 150°C
lead solder duration (+300°C) 10sec
Note: Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure to maximum ratings for extended periods may affect device reliability.
