MAX44259/MAX44260/ 1.8V, 15MHz Low-Offset, MAX44261/MAX44263 Low-Power, Rail-to-Rail I/O Op Amps General Description Benefits and Features
The MAX44259/MAX44260/MAX44261/MAX44263 offer ● Low Noise for Higher System Accuracy a unique combination of high speed, precision, low noise, • 12.7nV/√Hz Input Voltage-Noise Density and low-voltage operation making them ideally suited for a • 1.2fA/√Hz Input Current-Noise Density large number of signal processing functions such as filter- • 50µV (max) VOS at +25°C ing and amplification of signals in portable and industrial • 110dB Total Harmonic Distortion equipment. ● 15MHz Unity-Gain Bandwidth Enables for High- The devices’ rail-to-rail input/outputs and low noise Bandwidth Applications guarantee maximum dynamic range in demanding appli- ● Low Power Extends the Battery Life of Portable cations such as 12- to 14-bit SAR ADC drivers. Unlike Equipment traditional rail-to-rail input structures, input crossover dis- • 500fA Low Input Bias Current tortion is absent due to an optimized input stage with an • 750µA Quiescent Current per Amplifier ultra-quiet charge pump. • < 1µA Supply Current in Shutdown The MAX44260 includes a fast-power-on shutdown mode ● On-Demand VOS Self-Calibration (MAX44261) for further power savings. The MAX44261 offers a unique ● Saves Board Space on-demand calibration pin where the user can invoke self- • Small, 2mm x 2mm SC70 and 1mm x 1.5mm Thin trimming of the input offset voltage. The MAX44263 is a µDFN (MAX44260) and SOT23 (MAX44259) dual amplifier. Packages The family of parts operates from a supply range of 1.8V ● Wide Supply Range from 1.8V to 5.5V Simplifies to 5.5V over the -40NC to +125NC temperature range Power-Supply Requirements and can operate down to 1.7V over the 0NC to +70NC temperature range. The MAX44259 is offered in a 5-pin
