Texas Instruments OPA4488 Operational Amplifiers
Texas Instruments OPA4488 Operational Amplifiers are 48V, wide-bandwidth, low noise, zero-drift, and Mux-friendly Operational Amplifiers (op amps). These amplifiers feature 7.5µV offset voltage (maximum) and 0.025µV/°C offset voltage drift (maximum) over a wide temperature range. The OPA4488 operational amplifiers include a 4.5V to 48V supply voltage range, 1.5mA low quiescent current, and -40°C to 125°C operating temperature range. These OP amps provide a combination of high precision, fast settling, and low noise. The OPA4488 operational amplifiers are available in industry-standard and micro-size packages to fit the most space-constrained applications. Typical applications include battery test equipment, a weigh scale, an analog input module, a pressure transmitter, a programmable DC power supply, and a semiconductor test.
