AMC1301DWVR – TEXAS INSTRUMENTS

The Texas Instruments AMC1301DWVR is a single-channel, low-power, precision instrumentation amplifier in a tiny 6-pin SOT-23 package. It boasts a high input impedance exceeding 10GΩ, enabling accurate signal acquisition from high-impedance sources with minimal loading effects. The device operates from a single 2.7V to 5.5V supply, making it suitable for battery-powered applications. Its gain is externally set via a single resistor, offering flexibility from 1 to 1000, and features a low input offset voltage of typically 25µV, crucial for precision measurements. The AMC1301DWVR’s low noise (typically 18nV/√Hz) ensures accurate signal amplification even in noisy environments. Common applications include biomedical sensors, industrial process monitoring, and precision data acquisition systems requiring high accuracy and low power consumption. Its small form factor and surface-mount packaging contribute to compact and efficient circuit designs. The internal chopper stabilization minimizes drift and offsets over temperature, enhancing long-term stability. However, designers should note the relatively low bandwidth (approximately 10kHz), limiting its use in high-frequency applications.
