Texas Instruments ADS8321 16-Bit, High Speed, MicroPower Sampling Analog-to-Digital Converter ADS8321E/2K5G4

The ADS8321E/2K5G4 is a 16-bit, high-speed, micro-power sampling analog-to-digital converter (ADC) from Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features a maximum sampling rate of 100kHz while consuming only 4.5mW of power at this rate. At lower sampling rates, the power consumption can drop to as low as 1mW at 10kHz, with a power-down mode that limits current draw to a maximum of 3µA. This ADC supports a bipolar input range and includes a synchronous serial interface (SPI/SSI compatible), making it suitable for various applications such as battery-operated systems, remote data acquisition, and industrial controls. The device is packaged in an MSOP-8 format and is pin-compatible with other Texas Instruments ADCs like the ADS7816 and ADS7822. The reference voltage can be set between 500mV and VCC/2, providing flexibility for different applications. The ADS8321 is designed for low power consumption and compact size, making it ideal for portable and battery-powered devices.
