Microchip Technology, Inc. Analog to Digital Converters (ADC) MCP33151-10T-E/MS

The MCP33151-10T-E/MS is a 14-bit, single-ended input successive approximation register (SAR) analog-to-digital converter (ADC) capable of a sample rate of 1 Msps. It operates with an analog supply voltage (AV_{DD}) of 1.8V and supports a digital input/output interface voltage (DV_{IO}) ranging from 1.7V to 5.5V. The device features low power consumption, drawing approximately 0.66 mA during conversion and 1.5 ¬µA in standby mode. It utilizes a pseudodifferential input configuration with a full-scale input range from 0V to the external reference voltage (V_{REF}), which can be set between AV_{DD} and 5.1V. The MCP33151-10T-E/MS includes automatic self-calibration for offset, gain, and linearity errors, ensuring accurate performance across its specified temperature range of -40¬8C to +125¬8C. It communicates via a SPI-compatible 3-wire interface, allowing for easy integration with various host devices. Typical applications include high-precision data acquisition, medical instruments, and battery management systems. The device is available in a compact MSOP-10 package, making it suitable for space-constrained designs.
