GENERAL DESCRIPTION
The AD7298-1 is a 10-bit, high speed, low power, 8-channel,
successive approximation ADC. The part operates from a single
3.3 V power supply and features throughput rates up to 1 MSPS.
The device contains a low noise, wide bandwidth track-and-hold
amplifier that can handle input frequencies in excess of 30 MHz.
The AD7298-1 offers a programmable sequencer, which enables
the selection of a preprogrammable sequence of channels for
conversion. The device has an on-chip, 2.5 V reference that can
be disabled to allow the use of an external reference.
The device offers a 4-wire serial interface compatible with SPI and
DSP interface standards.
The AD7298-1 uses advanced design techniques to achieve very
low power dissipation at high throughput rates. The part also
offers flexible power/throughput rate management options. The
part is offered in a 20-lead LFCSP package.
PRODUCT HIGHLIGHTS
1. Ideally Suited to Monitoring System Variables in a Variety
of Systems. This includes telecommunications, and process
and industrial control.
2. High Throughput Rate of 1 MSPS with Low Power
Consumption.
3. Eight Single-Ended Inputs with a Channel Sequencer. A
consecutive sequence of channels can be selected on which
the ADC cycles and converts.
