EVALUATION KIT AVAILABLE MAX44291/MAX44292/ 36V, Single/Dual/Quad, Low-Noise Amplifiers MAX44294 with Maximum 0.5V/C Offset Drift General Description Benefits and Features The MAX44291/MAX44292/MAX44294 are single/dual/ Low Input Noise and High Bandwidth to Drive quad low-noise, precision operational amplifiers. The low Precision ADCs offset and low noise specifications and high supply range 4.9nV/Hz Low Input Noise make the MAX44291/MAX44292/MAX44294 ideal for 10MHz Gain-Bandwidth Product sensor interfaces, loop-powered systems, and various Low Input Offset Ensures Accurate Results Over types of medical and data acquisition instruments. Temperature The MAX44291/MAX44292/MAX44294 operate with a 125V (max) Low Input Offset Voltage wide supply voltage range from a 4.5V to 36V single 0.5V/C (max) Offset Drift supply or dual 2.25V to 18V supplies, and consume only 1.2mA/channel (typ). The MAX44291 features a Low 1.2mA Quiescent Current (Per Channel) Does Not Break the Power Budget shutdown input that reduces the supply current to 1A/ channel (typ) when in shutdown mode. ESD Protection Provides Robust Front-End The rail-to-rail output swing maximizes the dynamic range 8kV Human Body Model 1kV Charged Device Model when driving high-resolution ADCs even with low supply voltage. These devices achieve 10MHz of gain-bandwidth Wide Supply for High-Voltage Front-Ends product. Single 4.5V to 36V or Dual 2.25V to 18V Supply The MAX44291/MAX44292/MAX44294 are available in Ranges 8-pin MAX (single), 8-pin SO (dual), and 14-pin SO 8-Pin MAX and 8-/14-Pin SO Packages Save Board (quad) packages and are specified over the -40C to Space +125C automotive temperature range.
