GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

1. First 16-bit ADC in a SOT-23 package.

The AD7680 is a 16-bit, fast, low power, successive

approximation ADC. The part operates from a single 2.5 V to

5.5 V power supply and features throughput rates up to 100 kSPS.

The part contains a low noise, wide bandwidth track-and-hold

amplifier that can handle input frequencies in excess of 7 MHz.

2. High throughput with low power consumption.

3. Flexible power/serial clock speed management. The

conversion rate is determined by the serial clock, allowing

the conversion time to be reduced through the serial clock

speed increase. This allows the average power consumption

to be reduced when a power-down mode is used while not

converting. The part also features a shutdown mode to

maximize power efficiency at lower throughput rates.

Power consumption is 0.5 μA max when in shutdown.

The conversion process and data acquisition are controlled

using

with microprocessors or DSPs. The input signal is sampled on

and the serial clock, allowing the devices to interface

the falling edge of

and the conversion is also initiated at this

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

4. Reference derived from the power supply.

5. No pipeline delays.

The AD7680 uses advanced design techniques to achieve very

low power dissipation at fast throughput rates. The reference for

the part is taken internally from V_DD, which allows the widest

dynamic input range to the ADC. Thus, the analog input range

for this part is 0 V to V_DD. The conversion rate is determined by

the SCLK frequency.

This part features a standard successive approximation ADC

with accurate control of the sampling instant via a

once-off conversion control.
