GENERAL DESCRIPTION

Table 1.

Part Number

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.

with microprocessors or DSPs. The input signal is sampled on

the falling edge of , and the conversion is also initiated at this

point. There are no pipeline delays associated with the part.

2. AD7476/AD7477/AD7478 and AD7476A/AD7477A/

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. Reference derived from the power supply.

6. No pipeline delay. The parts feature a standard successive

approximation ADC with accurate control of the sampling

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.
