AD783JQ

完整的超高速采样和保持放大器 Complete Very High Speed Sample-and-Hold Amplifier

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.
