AD781: High speed, monolithic SHA with a max acquisition time for 700 ns to 0.01% over temperature.
Product Description
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.
