GENERAL DESCRIPTION
The AD7276/AD7277/AD7278 are 12-/10-/8-bit, high speed,
low power, successive approximation analog-to-digital converters
(ADCs), respectively. The parts operate from a single 2.35 V
to 3.6 V power supply and feature throughput rates of up to
3 MSPS. The parts contain a low noise, wide bandwidth track-
and-hold amplifier that can handle input frequencies in excess
of 55 MHz.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the devices to interface
with microprocessors or DSPs. The input signal is sampled on
the falling edge of CS, and the conversion is also initiated at this
point. There are no pipeline delays associated with the part.
The AD7276/AD7277/AD7278 use advanced design techniques
to achieve very low power dissipation at high throughput rates.
The reference for the part is taken internally from VDD. This
allows the widest dynamic input range to the ADC; therefore,
the analog input range for the part is 0 to VDD. The conversion
rate is determined by the SCLK.

PRODUCT HIGHLIGHTS
1.
3 MSPS ADCs in a 6-lead TSOT package.
2.
AD7478A pin-compatible.
3.
High throughput with low power consumption.
4.
Flexible power/serial clock speed management. This allows
maximum power efficiency at low throughput rates.
5.
