ROHM Unveils World’s Lowest Power Ultra-Compact CMOS Op Amp for Space-Constrained Sensing Applications

ROHM Co., Ltd. has announced that its ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry's lowest operating circuit current (*1). This IC is optimized to be applied as a measurement-sensing amplifier in size-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors.

ROHM has advanced its process, packaging, and proprietary Nano Energy (TM) (*2) circuit technologies to develop an op amp that addresses three key requirements: lower power consumption, higher accuracy, and compact size. The newly developed TLR1901GXZ achieves an ultra-compact footprint of less than 1mm2 by adopting a WLCSP (wafer-level chip scale package) with a fine ball pitch of 0.35mm while delivering an industry-leading low operating current of 160nA (typ.).

Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. A maximum input offset voltage temperature drift of 7uV per degrees Celsius ensures high accuracy operation over the operating temperature range.
