AD7298-1BCPZ

AD7298-1 is a 10bit, high-speed, low-power, 8-channel, successive approximation ADC. The part operates from a single 3.3V power supply and features throughput rates up to 1MSPS. The device contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 30MHz. This offers a programmable sequencer, which enables the selection of a preprogrammable sequence of channels for conversion. The device has an on-chip, 2.5V 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. This uses advanced design techniques to achieve very low power dissipation at high throughput rates.
