ROHM Semiconductor has developed the TLR1901GXZ, an ultra-compact CMOS operational amplifier that achieves the industry’s lowest operating circuit current. This IC is ideal for handheld measurement instruments, wearable devices, and indoor motion detectors as demand grows for more sophisticated control in battery-driven devices. The TLR1901GXZ features an ultra-compact footprint of less than 1mm2 and an industry-leading low operating current of 160nA (typ.). It also has an exceptionally low input offset voltage of just 0.55mV (max.) and a maximum input offset voltage temperature drift of 7uV/°C, ensuring high-accuracy performance.

ROHM will continue to pursue further power savings in op amps by advancing miniaturization and ultra-low power technologies. The company is committed to reducing noise and offset, expanding power supply voltage ranges, and contributing to solving social issues through more precise application control. Nano Energy™ technology is a proprietary ultra-low current consumption technology that contributes to extending the operating time of battery-powered IoT and mobile devices, as well as improving efficiency in industrial and automotive equipment.

Online sales for the TLR1901GXZ are now available through distributors like DigiKey and Mouser. The IC can be paired with ROHM’s ultra-compact general-purpose resistors for enhanced design flexibility. The MCR004 series includes lead-free options for sustainable designs. Adapter boards featuring SSOP5 package ICs are also available to facilitate evaluation and replacement considerations.
