The AD7298 is a 12-bit, high speed, low power, 8-channel, successive approximation ADC with an internal temperature sensor. 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 70 MHz. The AD7298 offers a programmable sequencer, which enables the selection of a pre-programmable 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 AD7298 includes a high accuracy band-gap temperature sensor, which is monitored and digitized by the12-bit ADC to give a resolution of 0.25C. The device offers a 4-wire serial interface compatible with SPI, and DSP interface standards. The AD7298 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.
