● 150ns max SAMPLE-TO-HOLD SETTLING
TIME
● 24-PIN HERMETICALLY-SEALED METAL
PACKAGE
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/µs.
This component is capable of accurately digitizing fast
changing signals at sample rates as high as 500k
samples per second.
DESCRIPTION
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 digital inputs (HOLD and HOLD) are TTL-
compatible. 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 dual-
in-line hermetic metal package. SHC804 is pin-com-
patible with other sample/holds on the market with
similar performance characteristics.
