Product Details
●The AD781 is a high speed monolithic sample-and-hold amplifier (SHA). The AD781 guarantees a maximum acquisition time for 700 ns to 0.01% over temperature. The AD781 is specified and tested for hold mode total harmonic distortion and hold mode signal-to-noise and distortion. The AD781 is configured as a unity gain amplifier and uses a self-correcting architecture that minimizes hold mode errors and insures accuracy over temperature. The AD781 is self-contained and requires no external components or adjustments.
●The low power dissipation, 8-pin mini-DIP package and completeness make the AD781 ideal for highly compact board layouts. The AD781 will acquire a full-scale input in less than 700 ns and retain the held value with a droop rate of 0.01 µV/µs. Excellent linearity and hold mode dc and dynamic performance make the AD781 ideal for 12- and 14-bit high speed analog-to-digital converters.
●The AD781 is manufactured on Analog Devices" BiMOS process which merges high performance, low noise bipolar circuitry with low power CMOS to provide an accurate, high speed, low power SHA.
●The AD781 is specified for three temperature ranges. The J grade device is specified or operation form 0°C to 70°C , the A grade form -40°C to +85°C and the S grade from -55°C to +125°C . The J and A grades are available in 8-pin plastic DIP packages. The S grade is available in an 8-pin cerdip package.
