The 1B32 is a precision, chopper‑based signal‑conditioning component designed for high‑accuracy load‑cell and bridge transducer applications. It combines a low‑noise amplifier, a three‑pole low‑pass filter and a programmable bridge excitation source in a compact 28‑pin double‑DIP package.
The manual details the device’s gain options, remote‑sensing capability, power‑supply requirements, input protection, and application examples such as pressure transducer interfaces and mobile data‑acquisition systems.
| Gain Accuracy | ±0.1 % |
|---|---|
| Gain Temperature Coefficient | +2 ppm/°C (typ) / +6 ppm/°C (max) |
| Low‑Pass Filter Cutoff Frequency | 4 Hz (‑3 dB point) |
| Power‑Supply Operating Voltage | +12 V to +18 V |
| Common‑Mode Rejection (CMR) | ≥140 dB at 60 Hz, G=1000 V/V |
The bridge excitation can be programmed from +4 V to +15 V.
The low‑pass filter has a 3 dB cutoff frequency of 4 Hz.
The input offset temperature coefficient is +0.07 µV/°C (RTI).
The device is rated for an operating supply of +12 V to +18 V.
