MAX44250 datasheet


Description :

The MAX44250, MAX44251, MAX44252 are 20V, ultra precision, low-noise, low-drift amplifiers that offer near zero DC offset and drift through the use of patented auto
correlating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise.

These single, dual, and quad devices feature rail-to-rail outputs, operate from a single 2.7V to 20V supply or dual ±1.35V to ±10V supplies and consume only 1.15mA per channel, while providing 5.9nV/√Hzinput-referred voltage noise. The ICs are unity-gain stable with a gain bandwidth product of 10MHz. With excellent specifications such as offset voltage of 6µV (max), drift of 19nV/°C (max), and 123nVP-Pnoise in 0.1Hz to 10Hz, the ICs are ideally suited for applications requiring ultra-low noise and DC precision such as interfacing with pressure sensors, strain gauges, precision weight scales, and medical instrumentation.

1. 2.7V to 20V Power-Supply Range

2. Integrated EMI Filter

2. 6µV Input Offset Voltage (max) at Room Temperature

3. TCVOSof 19nV/°C (max)

MAX44280 datasheet


Description :

The MAX44280 offers a unique combination of high speed, precision, low noise, and low-voltage operation making it ideally suited for a large number of signal processing functions such as filtering and amplification of signals in portable and industrial equipment. The amplifier features an input offset of less than 50FV and a high-gain bandwidth product of 50MHz while maintaining a low 1.8V supply rail. The device is internally compensated for gains of 5V/V or greater. The device’s rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12- to 16-bit SAR ADC drivers. Unlike traditional rail-to-rail input structures, input crossover distortion is absent due to an optimized input stage with an ultra-quiet charge pump.

The device includes a fast-power-on shutdown mode for further power savings. The IC operates from a supply range of 1.8V to 5.5V over the -40NC to +125NC temperature range and can operate down to 1.7V over the 0NC to +70NC temperature range. The MAX44280 is available in a small,6-pin SC70 package and is also available in a 1mm x 1.5mm thin µDFN (ultra-thin LGA) package.

Features :

1. Low 1.8V Supply Rail Over the -40°C to +125°C Range
2. 1.7V Supply Rail Over the 0°C to +70°C Range
3. 50MHz Bandwidth
4. Low 12.7nV/√HzInput Voltage-Noise Density
5. Low 1.2fA/√HzInput Current-Noise Density
6. Low 50µV (max) VOSat +25°C
7. 500fA Low Input Bias Current
8. 750µA Quiescent Current per Amplifier
9. < 1µA Supply Current in Shutdown
10. Small, 2mm x 2mm SC70 and 1mm x 1.5mm Thin µDFN Packages
11. Low -110dB Total Harmonic Distortion
12. 5V/V Minimum Stable Gain
