1MSPS,
10- / 12-Bit ADCs in 6 Lead SOT-23
using
CS
and the serial clock, allowing the devices to
interface with microprocessors or DSPs. T he input signal
is sampled on the falling edge of
CS
and the conversion is
also initiated at this point. T here are no pipelined delays
associated with the part.
T he AD7476/AD7477 use advanced design techniques to
achieve very low power dissipation at high throughput
rates.
T he reference for the part is taken internally from V
DD.
T he analog input range for the part is 0 to V
DD
. T he con-
version rate is determined by the SCLK .

T he AD7476/AD7477 are 12-bit and 10-bit, high speed,
low power, successive-approximation ADC s respectively.
T he parts operate from a single 2.35 V to 5.25 V power
supply and feature throughput rates up to 1MSPS. T he
parts contain a low-noise, wide bandwidth track/hold am-
plifier which can handle input frequencies in excess of
1M H z.
T he conversion process and data acquisition are controlled

1. First 10-/12-Bit ADCs in a SOT -23 package.
2. High T hroughput with Low Power Consumption
3. Flexible Power/Serial Clock Speed Management
T he conversion rate is determined by the serial clock
allowing the conversion time to be reduced through the
serial clock speed increase. T his allows the average power
cunsumption to be reduced when a powerdown mode is
used while not converting. T he part also features a shut-
down mode to maximize power efficiency at lower
throughput rates. Power consumption is 1
μ
A max when
in shutdown.
4. No Pipeline Delay
T he part features a standard successive-approximation
ADC with accurate control of the sampling instant via a
CS
input and once off conversion control.
