GENERAL DESCRIPTION
The AD7466/AD7467/AD7468 are 12-/10-/8-bit, high
speed, low power, successive-approximation ADCs
respectively. The parts operate from a single 1.6V to 3.6V
power supply and feature throughput rates up to 200kSPS.
The parts contain a low-noise, wide bandwidth track/hold
amplifier which can handle input frequencies in excess of
TBDkHz.
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 pipelined delays
associated with the part.
The AD7466/AD7467/AD7468 use advanced design tech-
niques 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.
Thus the analog input range for the part is 0 to VDD. The
conversion rate is determined by the SCLK.
PRODUCT HIGHLIGHTS
1. Specified for Supply voltages of 1.6V to 3.6V.
2. 8-/10-/12-Bit ADCs in a SOT-23 package.
3. High Throughput rate with Low Power Consumption.
4. 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. Automatic Power down after
conversion, which allows the average power consumption
to be reduced when in power down. Current consump-
tion is 0.5
A max when in power down.
5. Reference derived from the power supply.
6. No Pipeline Delay.
The part features a standard successive-approximation
ADC with accurate control of the conversions via a
CS
input.
