TEXAS INSTRUMENTS AND NATIONAL SEMICONDUCTOR DELIVER MORE TOGETHER
EMI Hardened Sensor Interface Solution
Description:
One of the most prevalent frequencies used today is 2.4GHz. It is used for
cell phones, WiFi, industrial communications, etc. One of the challenges in
any precision application is keeping the signal path from being affected by
this radiated noise. Filtering works on the input connections but the
LMP2021 actually filters the signal internally to the amplifier. This is
especially beneficial in high gain applications. Coupled with a precision ADC
from TI and the result is a more reliable and secure high precision
measurement.
Key Features:
Single and dual precision operational amplifiers
o Ultra low input offset voltage, near zero input offset voltage drift,
very low input voltage noise and very high open loop gain.
o Ideal for instrumentation and sensor interfaces
Only 0.004 µV/°C of input offset voltage drift
o Provides great precision in high accuracy applications
Proprietary continuous correction circuitry
o Guarantees impressive CMRR and PSRR, removes the 1/f noise
component, and eliminates the need for calibration in many
circuits.
High-linearity, low-drift, 24-bit, analog-to-digital converter (ADC)
