Microchip’s Pipelined Analog-to-Digital Converters offer 16-bit resolution with sampling speeds up to 200 Msps.

Microchip’s Delta-Sigma ADC families offer 16 to 24-bits of resolution with sampling rates from 4 sps to over 100 ksps.

Microchip's SAR (Successive Approximation Register) ADC offering provides a broad selection for low power applications. These devices operate with an active conversion current as low as 175 µA.

Microchip offers a wide variety of display ADCs, which provide a complete data acquisition system on a chip.

Noise rejection of 50/60 Hz and flexible speed vs. resolution configuration make these devices suitable for a variety of data acquisition systems.

High precision plus industry standard interfaces and pinouts make these devices fit in applications such as sensor interfaces, process controls, panel meters, instrumentation.
