Precision low-noise dual operational amplifier offers true-zero output

Maxim's MAX44267 single-supply dual operational amplifiers are now available from Mouser stock. The precision, low-noise, low-drift dual operational amplifiers offer true-zero output. This 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 still as effective as a normal dual-rail ±4.5V to ±15V amplifier. The architecture of this device eliminates the need for a negative power-supply rail, saving system cost and size. In support, Mouser also stocks the Maxim MAX44267EVKIT Evaluation Kit which provides a proven design for evaluating the MAX44267. The kit uses a proven PCB layout and is fully assembled and tested. Each evaluation kit circuit is pre-configured as non-inverting amplifiers. They can be adapted to other topologies by changing a few components. The evaluation kit comes with an MAX44267AUD+ already installed.
