?The HTCSEMI HT8631BRTZ SOT-23-5 Operational Amplifier is a low-cost, low-power, precision operational amplifier designed for use in audio, low frequency, and low voltage applications. It provides high gain with a wide bandwidth (4500V/µs for the standard version and 7400V/µs for the high speed version). This device is ROHS compliant and features high power supply rejection ratio (PSRR: 80dB), low input bias current (1pA), and low offset voltage (150uV) to enhance its accuracy and performance. The output stage is designed to ensure even more stability with a slew rate of up to 35V/µs. It is supplied in a SOT-23-5 package, which is ideal for a wide range of applications where board space is limited.
