HT4040BRTZ

The HT4040 are CMOS op-amps with low offset, stable high frequency response, low power, low supply voltage, and rail-to-rail inputs and outputs. HT4040 have a high gain-bandwidth product of 6MHz, 3.7V/us slew rate while consuming only 330μμ of supply current per amplifier. The maximum input offset voltage is 200uV for HT4040. Beyond the rail input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range. The operating range is from 2.5V to 5.5V. This combination of features makes the HT4040 superior among rail-to-rail input/output CMOS op amps in its power class. It is specified over the extended industrial temperature rang -40°C to ±125°C. The HT4040 can be used as cost-effective plug-in replacements for many commercially available op amps to reduce power and improve input/output range
