The AMP01 is a monolithic instrumentation amplifier designed for high-precision data acquisition and instrumentation applications. The design combines the conventional features of an instrumentation amplifier with a high current output stage. The output remains stable with high capacitance loads (1 µF), a unique ability for an instrumentation amplifier. Consequently, the AMP01 can amplify low level signals for transmission through long cables without requiring an output buffer. The output stage may be configured as a voltage or current generator. Input offset voltage is very low (20 µV), which generally eliminates the external null potentiometer. Temperature changes have minimal effect on offset; TCVIOS is typically 0.15 µV/°C. Excellent low-frequency noise performance is achieved with a minimal compromise on input protection. Bias current is very low, less than 10 nA over the military temperature range. High common-mode rejection of 130 dB, 16-bit linearity at a gain of 1000, and 50 mA peak output current are achievable simultaneously.
The AMP01 is a monolithic instrumentation amplifier designed for high‑precision data acquisition. It offers ultra‑low offset voltage (20 µV), very low noise (0.12 µV p‑p from 0.1 Hz to 10 Hz), high output drive (+10 V at 50 mA) and stable operation with capacitive loads up to 1 pF.
Key specifications include a gain range of 0.1 to 10 000, 125 dB CMRR at a gain of 1000, a 26 MHz gain‑bandwidth product at G=1000, and output voltage swing of about +13 V into a 500 Ω load. The device is available in several packages such as 18‑lead ceramic leaded (Q‑18) and 28‑terminal LCC (E‑28A).
