General Description
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 MAX package.
These devices use a spread-spectrum, autozeroing
technique that constantly measures and corrects the
input offset, eliminating drift over time and temperature and
the effect of 1/f noise. This technique achieves less than
20V offset voltage, allows ground-sensing capability, pro-
vides ultra-low CMOS input bias current and increased
common-mode rejection performance.
The MAX4208/MAX4209 provide high-impedance inputs
optimized for small-signal differential voltages (±100mV).
All devices provide a gain-bandwidth product of 750kHz.
The MAX4208 provides an adjustable gain with two
external resistors or unity gain with FB connected to OUT.
The MAX4209 is available with a fixed gain of 100V/V with
±0.03% (typ) accuracy. 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 750A
of quiescent current (when the internal buffer is off) and
only 1.4A in shutdown mode. These amplifiers
also operate with ±2.5V dual supplies with REF
connected to ground and REFIN/MODE to VSS.
The MAX4208/MAX4209 are available in space-saving
8-pin MAX packages and are specified over the auto-
motive operating temperature range (-40°C to +125°C).
