Product Details
●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 µV/µs. 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.
