The new TLR377GYZ combines ultra-compact size with exceptional accuracy, setting a new standard for high-precision sensing in shrinking tech devices.

ROHM has announced the release of the TLR377GYZ, the smallest rail-to-rail CMOS operational amplifier (op amp) designed for smartphones and IoT devices. This groundbreaking component, operating from 1.8V to 5V, addresses the growing demand for miniaturized yet high-precision components needed in today's compact technology.

As smartphones and IoT devices continue to shrink, there is an increasing need for smaller, more efficient components that can handle precise signal amplification. The TLR377GYZ meets this challenge by combining ultra-small size with high accuracy, a feat that has traditionally been difficult to achieve with conventional op amps.

ROHM has leveraged years of expertise in circuit design, process, and packaging to develop this advanced op amp. The TLR377GYZ features a maximum input offset voltage as low as 1mV, achieved without enlarging the transistors, and reduced flicker noise thanks to proprietary process technology. The result is an input equivalent noise voltage density of just 12nV/√Hz, reflecting an impressive reduction in noise.

The op amp is housed in a wafer-level chip scale package (WLCSP) with a ball pitch of only 0.3mm, shrinking the size by approximately 69% compared to conventional products. This design choice helps accommodate the trend of increasingly smaller devices.

To facilitate easy integration, ROHM also offers an IC-mounted conversion board that can replace SSOP6 packages, making it easier for users to evaluate and implement the new component. Additionally, the high-accuracy SPICE model, known as ROHM Real Model, is available on ROHM’s website for verification simulations.
