Ultra-Low Offset/Drift, Precision

General Description

Ultra-Low Input Offset Voltage

Low 20±µV/°C Offset Voltage Drꢂft  
1pA CMOS Input Bꢂas Current  
The MAX4208/MAX4209 ultra-low offset and drift instru-  
mentation amplifiers feature exceptional precision specifi-  
cations, low power consumption, rail-to-rail output,  
excellent gain-bandwidth product, and buffered  
REFIN/MODE input in a very small µMAX® package.  
These devices use a patentedspread-spectrum,  
autozeroing technique that constantly measures and  
corrects the input offset, eliminating drift over time and tem-  
perature and the effect of 1/f noise. This technique  
achieves less than 20µV offset voltage, allows ground-  
sensing capability, provides ultra-low CMOS input bias cur-  
rent and increased common-mode rejection performance.

ꢄ52µA Supply Current  
The MAX4208/MAX4209 provide high-impedance inputs  
optimized for small-signal differential voltages ( 100mV).  
All devices provide a gain-bandwidth product of 750kHz.

Operate Over the -.2°C to +1±5°C Automotꢂve  
The MAX4208 provides an adjustable gain with two  
external resistors or unity gain with FB connected to OUT.  
The MAX4209 is available in fixed gains of 10V/V, 100V/V,  
or 1000V/V (suffixed T, H, and K) with 0.0ꢀ3 (typ) accu-  
racy. Both devices include a reference input (REF) to  
level-shift the output, allowing for bipolar signals in single-  
supply applications. In both devices, REFIN/MODE is an  
input to a precision unity-gain buffer, which sets the REF  
voltage to level-shift the output. The internal REF buffer  
allows the reference to be set by a simple resistive divider  
or an ADC reference without any loading error.

The MAX4208/MAX4209 operate with a 2.85V to 5.5V  
single-supply voltage and consume only 750µA  
of quiescent current (when the internal buffer is off) and  
only 1.4µA in shutdown mode. These amplifiers  
also operate with 2.5V dual supplies with REF
