AD7298BCPZ Datasheet PDF - ADI

●The AD7298BCPZ is a 12-bit high speed low power 8-channel successive approximation Analog-to-digital Converter (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 30MHz. It offers a programmable sequencer, which enables the selection of a pre-programmable 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. It includes a high accuracy band gap temperature sensor, which is monitored and digitized by the 12-bit ADC to give a resolution of 0.25°C. The device offers a 4-wire serial interface compatible with SPI and DSP interface standards. It uses advanced design techniques to achieve very low power dissipation at high throughput rates.

● Temperature sensor accuracy of ±1°C
