The AMP04 is a single supply instrumentation amplifier from Analog Devices that is designed to operate over a +5V to ±15V supply range. It offers an excellent combination of accuracy, low power consumption, wide input voltage range, and excellent gain performance. Gain is set by a single external resistor and can be from 1 to 1000. Input common-mode voltage range allows the AMP04 to handle signals with full accuracy from ground to within 1 volt of the positive supply. And the output can swing to within 1 volt of the positive supply. Gain bandwidth is over 700 kHz. In addition to being easy to use, the AMP04 draws only 700µA of current.
The AMP04 is a precision, single‑supply instrumentation amplifier designed for +5 V to +15 V operation. It offers low supply current (≈700 µA), low offset voltage (≤150 µV), single‑resistor gain setting from 1 to 1000, and high common‑mode rejection. The device is available in 8‑lead plastic DIP, ceramic DIP and SO‑8 surface‑mount packages.
Typical applications include strain‑gage measurement, thermocouples, RTDs, battery‑powered equipment, medical instrumentation, data‑acquisition systems and portable instruments. The handbook provides electrical characteristics, noise performance, programming guidelines, grounding recommendations and ordering information.
| Gain Range | 1 – 1000 V/V |
