High-Output-Drive, 10MHz, 10V/µs, Rail-to-Rail I/O Op Amps with Shutdown in SC70
General Description
The MAX4230–MAX4234 single/dual/quad, high-output
drive CMOS op amps feature 200mA of peak output cur-
rent, rail-to-rail input, and output capability from a single
2.7V to 5.5V supply. These amplifiers exhibit a high slew rate of 10V/μs and a gain-bandwidth product (GBWP) of
10MHz. The MAX4230–MAX4234 can drive typical head-set levels (32Ω), as well as bias an RF power amplifier (PA) in wireless handset applications.
The MAX4230 comes in a tiny 5-pin SC70 package
and the MAX4231, single with shutdown, is offered in a 6-pin SC70 package and in 1.5mm x 1.0mm UCSP and thin μDFN packages. The dual op-amp MAX4233 is
offered in the space-saving 10-bump chip-scale package (UCSP™), providing the smallest footprint area for a dual
op amp with shutdown.
These op amps are designed to be part of the PA control cir-cuitry, biasing RF PAs in wireless headsets. The MAX4231/
MAX4233 offer a SHDN feature that drives the output low. This ensures that the RF PA is fully disabled when needed, preventing unconverted signals to the RF antenna.
Applications
●RF PA Biasing Controls in Handset Applications●Portable/Battery-Powered Audio Applications●Portable Headphone Speaker Drivers (32Ω)●Audio Hands-Free Car Phones (Kits)●Tablet/Notebook Computers●Digital-to-Analog Converter Buffers●Transformer/Line Drivers●Motor Drivers

Detailed Description
Rail-to-Rail Input Stage

The MAX4230–MAX4234 CMOS operational amplifiers
have parallel-connected n- and p-channel differential
input stages that combine to accept a common-mode
range extending to both supply rails. The n-channel
stage is active for common-mode input voltages typically greater than (VSS + 1.2V), and the p-channel stage is
active for common-mode input voltages typically less than (VDD - 1.2V).
Applications Information
Package Power Dissipation
Warning: Due to the high output current drive, this op amp can exceed the absolute maximum power-dissipation rating.
As a general rule, as long as the
package power dissipation is not exceeded for any of the
package types offered. There are some exceptions to this
rule, however. The absolute maximum power-dissipation
rating of each package should always be verified using
the following equations. The equation below gives an approximation of the package power dissipation:
IC(DISS)RMSRMSPV I COS≅θ
where:
VRMS = RMS voltage from VDD to VOUT when sourcing current and RMS voltage from VOUT to VSS when sinking
current.
IRMS = RMS current flowing out of or into the op amp and
the load.
θ = phase difference between the voltage and the current.
