AD7476A 12-Bit, 1 MSPS, Low-Power A/D Converter in SC70 and MSOP Packages
First 12-/10-/8-bit ADCs in a SC70 package.
High throughput with low power consumption.
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 parts also feature a power-down mode to
maximize power efficiency at lower throughput rates.
Current consumption is 1 µA maximum and 50 nA
typically when in power-down mode.
Reference derived from the power supply.
No pipeline delay. The parts feature a standard successive
approximation ADC with accurate control of the sampling
instant via a CS input and once-off conversion control.
The AD7476A/AD7477A/AD7478A are 12-bit, 10-bit, and 8-bit
high speed, low power, successive-approximation analog-todigital
converters (ADCs), respectively. The parts operate from
a single 2.35 V to 5.25 V power supply and feature throughput
rates up to 1 MSPS. The parts contain a low noise, wide
bandwidth track-and-hold amplifier that can handle input
frequencies in excess of 13 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 parts. The AD7476A/AD7477A/
AD7478A use advanced design techniques to achieve low power
dissipation at high throughput rates. The reference for the part
is taken internally from VDD to allow 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.
