Product Overview

The MAX4234AUD+ is a high output drive, rail to rail I/O, quad CMOS operational amplifier (op-amp) in 14 pin TSSOP package. This amplifier exhibits high slew rate of 10V/µs and gain bandwidth product (GBWP) of 10MHz. The MAX4234 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. 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
  • Extends battery life, 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
  • 1.1mA supply current per amplifier (VDD = 2.7V, VCM = VDD/2)

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.
