Product Overview

The MAX4231AXT+T is a high output drive, rail to rail I/O, single CMOS operational amplifier (op-amp) with shutdown mode in 6 pin SC-70 package. This amplifier exhibits high slew rate of 10V/µs and gain bandwidth product (GBWP) of 10MHz. The MAX4231 can drive typical headset levels (32ohm) as well as bias an RF power amplifier (PA) in wireless handset applications. This op-amp is designed to be part of RF PA control circuitry and biasing RF power amplifiers in wireless headsets. The MAX4231 offers SHDN (complementary) feature that drives the output low. This ensures that the RF PA is fully disabled when needed, preventing unconverted signals to RF antenna. It is also used in audio hands free car phones kits, digital to analogue converter buffers, transformer/line drivers and high bandwidth applications.
  • Supply voltage range from ±1.35V to ±2.5V and 2.7V to 5.5V
  • Operating temperature range from -40°C to 125°C
  • Optimized for headsets and high current outputs
  • Output drive capability of 200mA
  • Large signal voltage gain of 100dB (RL = 100Kohm) at TA = +25°C
  • PSRR of 85dB (VDD = 2.7V to 5.5V) and CMRR of 70dB (VSS < VCM < VDD) at TA = +25°C
  • No phase reversal for overdriven inputs
  • Unity gain stable for capacitive loads to 780pF
  • Input offset voltage of 0.85mV and input offset current of 50pA at TA = +25°C
  • Low power shutdown mode reduces supply current to less than 1µA

Applications

Signal Processing, Portable Devices, Audio, Motor Drive & Control

Footnotes

Due to high output current drive, this op-amp can exceed the absolute maximum power dissipation rating.
