10-/12-Bit ADCs in 6-Lead SC70
GENERAL DESCRIPTION
The AD7910/AD7920 are, respectively, 10-bit and 12-bit, high peed, low power, successive-approximation ADCs. The partsoperate from a single 2.35 V to 5.25 V power supply and featurethroughput rates up to 250 kSPS. The parts contain a low noise,wide bandwidth track-and-hold amplifier that can handle inputfrequencies in excess of 13 MHz.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the devices to interfacewith microprocessors or DSPs. The input signal is sampled onthe falling edge of CS and the conversion is also initiated at thispoint. There are no pipeline delays associated with the part.The AD7910/AD7920 use advanced design techniques to achievevery low power dissipation at high throughput rates.
