GENERAL DESCRIPTION
The AD7466/AD7467/AD74681 are 12-/10-/8-bit, high speed,
low power, successive approximation analog-to-digital
converters (ADCs), respectively. The parts operate from a single
1.6 V to 3.6 V power supply and feature throughput rates up to
200 kSPS with low power dissipation. The parts contain a low
noise, wide bandwidth track-and-hold amplifier, which can
handle input frequencies in excess of 3 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 reference for the part is taken internally from VDD. This
allows the widest dynamic input range to the ADC. Thus, the
analog input range for the part is 0 V to VDD. The conversion
rate is determined by the SCLK.
1 Protected by U.S. Patent No. 6,681,332.
PRODUCT HIGHLIGHTS
1.
Specified for supply voltages of 1.6 V to 3.6 V.
2.
12-, 10-, and 8-bit ADCs in SOT-23 and MSOP packages.
3.
High throughput rate with low power consumption.
Power consumption in normal mode of operation at
100 kSPS and 3 V is 0.9 mW maximum.
4.
Flexible power/serial clock speed management.
The conversion rate is determined by the serial clock,
allowing the conversion time to be reduced through
increases in the serial clock speed. Automatic power-down
after conversion allows the average power consumption to
be reduced when in power-down. Current consumption is
0.1 μA maximum and 8 nA typically when in power-down.
5.
Reference derived from the power supply.
6.
No pipeline delay.
7.
The part features a standard successive approximation
ADC with accurate control of conversions via a CS input.
