19-2164; Rev 8; 10/08  
High-Output-Drive, 10MHz, 10V/µs,  
Rail-to-Rail I/O Op Amps with Shutdown in SC70  
0–MAX234  
General Description  
Features  
The MAX4230–MAX4234 single/dual/quad, high-output-  
drive CMOS op amps feature 200mA of peak output  
current, 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 headset levels (32Ω), as well as bias an RF  
power amplifier (PA) in wireless handset applications.  
♦ 30mA Output Drive Capability  
♦ Rail-to-Rail Input and Output  
♦ 1.1mA Supply Current per Amplifier  
♦ 2.7V to 5.5V Single-Supply Operation  
♦ 10MHz Gain-Bandwidth Product  
♦ High Slew Rate: 10V/µs  
The MAX4230 comes in a tiny 5-pin SC70 package and  
the MAX4231, single with shutdown, is offered in the  
6-pin SC70 package and a 1.5mm x 1.0mm x 0.5mm  
ultra-thin µDFN package. The dual op-amp MAX4233 is  
offered in the space-saving 10-bump chip-scale pack-  
age (UCSP™), providing the smallest footprint area for  
a dual op amp with shutdown.  
♦ 100dB Voltage Gain (R = 100kΩ)  
L
♦ 85dB Power-Supply Rejection Ratio  
♦ No Phase Reversal for Overdriven Inputs  
♦ Unity-Gain Stable for Capacitive Loads to 780pF  
♦ Low-Power Shutdown Mode Reduces Supply  
Current to < 1µA  
These op amps are designed to be part of the PA con-  
trol circuitry, 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 dis-  
abled when needed, preventing unconverted signals to  
the RF antenna.  
♦ Available in 5-Pin SC70 Package (MAX4230)  
and 6-Pin, Thin µDFN Package (MAX4231)  
♦ Available in 10-Bump UCSP Package (MAX4233)  
Ordering Information  
The MAX4230 family offers low offsets, wide bandwidth,  
and high-output drive in a tiny 2.1mm x 2.0mm space-  
saving SC70 package. These parts are offered over the  
automotive temperature range (-40°C to +125°C).
