The AD783 is a high speed, monolithic sample-and-hold amplifier (SHA). The AD783 offers a typical acquisition time of 250 ns to 0.01%. The AD783 is specified and tested for hold mode total harmonic distortion with input frequencies up to 100 kHz. The AD783 is configured as a unity gain amplifier and uses a patented self-correcting architecture that minimizes hold mode errors and ensures accuracy over temperature. The AD783 is self-contained and requires no external components or adjustments.
The AD783 retains the held value with a droop rate of 0.02 mV/ms. Excellent linearity and hold mode dc and dynamic performance make the AD783 ideal for high speed 12- and 14-bit analog-to-digital converters.
The AD783 is manufactured on Analog Devices' ABCMOS process which merges high performance, low noise bipolar
circuitry with low power CMOS to provide an accurate, high speed, low power SHA.
The J grade device is specified for operation from 0°C to +70°C and the A grade from 40°C to +85°C. The J and A grades are available in 8-pin cerdip and SOIC packages. The military temperature range version is specified for operation from 55°C to +125°C and is available in an 8-pin cerdip package. For details refer to the Analog Devices Military Products Databook or AD783/883B data sheet.
