MAX44267 - Dual Op Amp

General Description

The MAX44267 precision, low-noise, low-drift dual operational amplifier offers true-zero output that allows the output to cross zero maximizing the dynamic range of an ADC and increasing resolution.

In addition, the input common-mode range extends from +13.5V down to -12V.

Key Features

  • low offset voltage of 50μV (max), drift of 0.4µV/°C (max), and 200nVP-P noise from 0.1Hz to 10Hz. The low offset and noise specifications and wide input common-mode range make the device ideal for sensor transmitters and interfaces. Varying the external charge pump capacitors enables the charge-pump noise to be minimized. The MAX44267 is part of a family of signal chain ICs including amplifiers, multiplexers and ADCs. These ICs eliminate the need for a negative supply to the multiplexer, amplifi.

MAX44267 +15V Single-Supply, Dual Op Amp with ±10V Output Range General Description The MAX44267 precision, low-noise, low-drift dual operational amplifier offers true-zero output that allows the output to cross zero maximizing the dynamic range of an ADC and increasing resolution. In addition, the input common-mode range extends from +13.5V down to -12V. The MAX44267 integrates charge-pump circuitry that generates the negative voltage rail in conjunction with external capacitors. This allows the amplifier to operate from a single +4.5V to +15V power supply, but it is as effective as a normal dual-rail ±4.5V to ±15V amplifier. The architecture eliminates the need for a negative power-supply rail, saving system cost and size.
