The LT1884/LT1885 op amps provide high accuracy input performance to amplifiers with rail-to-rail output swing and faster response compared to other precision amplifiers. The input offset voltage is trimmed to less than 50µV, and the low drift ensures accuracy over the operating temperature range. The maximum input bias currents are ultralow at 400pA. The amplifiers can operate on any total power supply voltage between 2.7V and 36V (fully specified from 5V to ±15V). The output voltage swings to within 40mV of the negative supply and 220mV of the positive supply, making them suitable for low voltage single supply operation. With a supply current of less than 1mA per amplifier, they offer superior response and settling time performance in a low power precision amplifier. The dual LT1884 is available in 8-pin SO and PDIP packages with standard pinouts. The quad LT1885 is also available in the standard pinout 14-pin SO package.
The LT1884 (dual) and LT1885 (quad) are precision rail‑to‑rail output operational amplifiers with ultra‑low offset voltage and bias current. They operate from 2.7 V to 36 V supplies and deliver up to 1 V/µs slew rate while consuming less than 1 mA per amplifier.
