EVALUATION KIT AVAILABLE MAX44259/MAX44260/MAX44261/MAX44263 1.8V, 15MHz Low-Offset, Low-Power, Rail-to-Rail I/O Op Amps General Description Benefits and Features S Low Noise for Higher System Accuracy The MAX44259/MAX44260/MAX44261/MAX44263 offer a unique combination of high speed, precision, low noise, 12.7nV/Hz Input Voltage-Noise Density and low-voltage operation making them ideally suited 1.2fA/Hz Input Current-Noise Density for a large number of signal processing functions such 50V (max) V at +25C OS as filtering and amplification of signals in portable and 110dB Total Harmonic Distortion industrial equipment. S 15MHz Unity-Gain Bandwidth Enables for High- Bandwidth Applications The devices rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding appli- S 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 500fA Low Input Bias Current distortion is absent due to an optimized input stage with 750A Quiescent Current per Amplifier an ultra-quiet charge pump. < 1A Supply Current in Shutdown The MAX44260 includes a fast-power-on shutdown mode S On-Demand V Self-Calibration (MAX44261) OS for further power savings. The MAX44261 offers a unique S Saves Board Space on-demand calibration pin where the user can invoke Small, 2mm x 2mm SC70 and 1mm x 1.5mm self-trimming of the input offset voltage. The MAX44263 Thin DFN (MAX44260) and SOT23 (MAX44259) is a dual amplifier. Packages The family of parts operates from a supply range of 1.8V S 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 Applications temperature range. The MAX44259 is offered in a 5-pin SOT23 package. The MAX44260/MAX44261 are avail- Notebooks able in small, 6-pin SC70 packages. The MAX44260 is also available in a 1mm x 1.5mm thin DFN (ultra-thin 3G/4G Handsets LGA) package. The MAX44263 is available in a small Portable Media Players 8-pin SC70 package.
