AD7298BCPZ

The AD7298BCPZ is a 12-bit successive approximation (SAR) analog-to-digital converter (ADC) from Analog Devices, featuring 8 single-ended input channels and a maximum sampling rate of 1 MSPS. It incorporates an on-chip temperature sensor with ±1°C accuracy and 0.25°C resolution, monitored through the ADC. The device supports both internal (2.5 V) and external reference options, and provides a 4-wire SPI/DSP-compatible serial interface.

The ADC operates from an analog supply voltage (VDD) of 2.8 V to 3.6 V and a separate logic interface supply (VDRIVE) of 1.65 V to 3.6 V. The analog input voltage range is 0 V to 2.5 V. Power consumption is low, with a power-down current of less than 10 µA. The device includes a programmable channel sequencer and an internal power-on reset.

Housed in a 20-lead LFCSP (4x4 mm) package with surface-mount mounting, the AD7298BCPZ is suitable for space-constrained applications. The operating temperature range is -40°C to +125°C, making it robust for industrial and automotive environments. With its high speed and integrated temperature sensing, this ADC is designed for multi-channel data acquisition systems requiring precise analog-to-digital conversion and temperature monitoring.
