PGA308

• Product Introduction

is a programmable PGA308 analog sensor signal conditioning. The analog signal amplifies the sensor signal path and provides digital calibration for offset and gain. Calibration is done through a 1W foot, a digital single-wire and UART-compatible interface. For three-terminal sensor modules, 1 week can be connected to V OUT and the OUT pin program V is passed. Gain and offset calibration parameters are stored in a bank of seven single-use programmable (OTP) memories on board. The bank of the Power-On Reset (POR) OTP can be programmed four times in total.

All analog signal paths include a 2×2-input multiplexer (MUX) that allows electronic sensor lead swapping, coarse offset adjustment, programmable gain instrument amplifier (PGA) with automatic zeroing, gain adjustment fine, fine offset adjustment, and programmable gain output amplifier.
