Precision instrumentation amp — 10 µV offset, 9-36 V supply
The PGA205BU is a single-channel instrumentation amplifier from Texas Instruments, delivering a 10 µV typical input offset voltage with 500 pA input bias current — the offset floor suits bridge-sensor and thermocouple front-ends where the error budget is in the microvolt range. Supply span runs from 9 V to 36 V single or dual supply, so the same part works on a ±15 V lab rail or a 12 V industrial bus without a separate regulator.
Bandwidth and slew rate — 1 MHz, 0.7 V/µs
The -3 dB bandwidth is 1 MHz with a 0.7 V/µs slew rate — adequate for 10-100 Hz sensor conditioning and multiplexed data acquisition, but the slew rate limits full-power bandwidth to roughly 110 kHz at 10 V output swing. Above that, the output distorts. Quiescent supply current is 5.2 mA, and each output can source or sink 23 mA — enough to drive a 10-bit SAR ADC input or a 4-20 mA transmitter stage directly.
Package and temperature grade — 16-SOIC, -40 to 85°C
Housed in a 16-SOIC wide-body (0.295-inch, 7.50 mm width) with supplier package designation 16-SOIC. The wide-body footprint matches the standard SOIC-16W land pattern — no fine-pitch tooling needed. Rated for -40°C to 85°C ambient, covering industrial temperature range. The tube packaging means the part ships in anti-static tubes, not tape-and-reel — factor this into pick-and-place feeder setup if converting to reel is required.
