Its front-end is a 2-channel differential multiplexer feeding a programmable gain amplifier (PGA), then the sigma-delta modulator — so you can switch between two sensor inputs and digitally adjust the gain without external op-amps. The reference is external, which means you pick the voltage reference that matches your sensor's full-scale range — a 2.5 V reference gives you 76 µV per LSB, a 5 V reference gives 152 µV per LSB. ## Supply rails and temperature range — the industrial fit At 500 SPS maximum, this is not a high-speed part — it is built for precision at low bandwidth. The sigma-delta architecture oversamples the input and digitally filters out noise, giving you clean 16-bit data at 10 Hz to 500 Hz output rates. ## Package reality — 16-SOIC wide body, tube delivery The AD7705BRZ comes in a 16-SOIC wide-body package (0.295\" body width, 7.50 mm), shipped in a tube. The wide-body SOIC has a 1.27 mm pitch, so it is hand-solderable and inspectable under a microscope — no X-ray needed. If your pick-and-place line is set up for tape-and-reel, the AD7705BRZ-REEL is the exact same die in reel packaging — same electrical specs, same footprint, just a different shipping format. No second-source cross-reference exists for this exact part — the AD7705BRZ is a single-source Analog Devices design.","metaTitle":"AD7705BRZ 16-Bit Sigma-Delta ADC, 500 SPS, 16-SOIC","metaDescription":"Analog Devices AD7705BRZ: 16-bit sigma-delta ADC, 2-channel differential, PGA, SPI interface, 500 SPS, 16-SOIC tube.
