LMP8100 – Programmable Gain Amplifier Delivers 0.03% Accuracy Over Temperature and<br />
Gain Settings ADC121S021<br />
Features<br />
• Unmatched gain accuracy for every gain setting enables<br />
accurate signal conditioning from -40°C to +125°C<br />
• Gain range 1 to 16 V/V in 1 V/V steps enables flexible and fine<br />
gain adjustments<br />
• Programmable frequency compensation increases usable<br />
bandwidth for all gain settings<br />
• Input zero calibration switch allows output offset voltage<br />
measurement and calibration<br />
• Glitch-free transition between programmed settings eliminates errors<br />
• 12 nV/√Hz input noise voltage accurately signal conditions in<br />
near DC-sensor applications<br />
• Ideal match for 12-bit, 1-channel ADCs up to 1 MSPS<br />
• Available in SOIC-14 packaging<br />
