The SHC804 is a high speed sample/hold amplifier designed for use in fast 12-bit data acquisition systems and signal processing systems.

The SHC804 acquires a 10V signal change in less than 350ns to ±1/2LSB at 12 bits. Throughput nonlinearity error is guaranteed to be within ±1/2LSB for 12-bit systems. Stability over temperature is excellent, with only ±5ppm/°C of gain drift and ±4ppm of FSR/°C of charge offset drift over the 25 to +85°C temperature range.

The ±25ps maximum aperture uncertainty of the SHC804 permits sampling (to ±0.01% of Full Scale Range) of signals with rates of change of up to 100V/ms. This component is capable of accurately digitizing fast changing signals at sample rates as high as 500k samples per second.

The digital inputs (HOLD and HOLD) are TTLcompatible. Power supply requirements are ±15V and +5V and the specification temperature range is 25°C to +85°C. The SHC804 is packaged in a 24-pin dualin- line hermetic metal package. SHC804 is pin-compatible with other sample/holds on the market with similar performance characteristics.
