The AD22057 is a single-supply difference amplifier for the amplification and low-pass filtering of small differential voltages from sources having a large common-mode voltage. Supply voltages from +3 V to +36 V can be used. The input common-mode range extends from below ground to 24 V using a +5 V supply with excellent rejection of this common-mode voltage. This range is achieved by the use of a special resitive attenuator at the input, laser trimmed to a very high differential balance. Low initial offset voltage and offset voltage drift are specified, and long-term stability of gain and offset voltage is also provided. Provisions are included for optional low-pass filtering and gain adjustment. An accurate midscale offset feature allows bipolar signals to be amplified. * Gain of ×20 Alterable from ×1 to ×160 * Input CMR from Below Ground to 6× (VS - 1 V) * Output Span 20 mV to (VS - 0.2) V * 1-, 2-, 3-Pole Low-Pass Filtering Available * Accurate Midscale Offset Capability * Differential Input Resistance 400 kΩ * Drives 1kΩ Load to +4 V Using VS = +5 V * Supply Voltage: +3.0 V to +36 V * Transient Spike Protection and RFI Filters Included * Peak Input Voltage (40 ms): 60 V * Reversed Supply Protection: -34 V * Operating Temperature Range: -40°C to +125°C https://elecena.pl/product/5067113/single-supply-sensor-interface-amplifier 2015-03-28 https://elecena.pl/product/5067113/single-supply-sensor-interface-amplifier 2018-03-28 https://elecena.pl/product/5067113/single-supply-sensor-interface-amplifier 2025-01-18
