Overview
The AD7960BCPZ is an 18-bit, 5 MSPS (Mega Samples Per Second) charge redistribution successive approximation (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the PulSAR® series and is known for its high performance in both noise and linearity. The AD7960 features a low power, high speed sampling ADC, an internal conversion clock, and an internal reference buffer. It operates over a wide temperature range from −40°C to +85°C and is packaged in a 32-lead LFCSP (QFN) with an exposed pad.
