ROHM Develops a New Op Amp that Minimizes Current Consumption, Improving Power Savings in Consumer and Industrial Equipment
ROHM has developed a linear operational amplifier (op amp) - LMR1901YG-M - featuring the lowest* current consumption in the industry. This makes it ideal for amplifying sensor signals used to detect and measure temperature, flow rate, gas concentration, and other parameters in applications powered by internal sources (i.e. batteries).
In recent years, advanced control has been in increasing demand for various applications in consumer and industrial electronics. Therefore, there is an increasing need for accurate sensing of parameters relevant to the application - such as, temperature, humidity, vibration, pressure, and flow rate. Op amps whose main function is to amplify sensor signals for subsequent detection and/or analog-to-digital conversion, is a crucial component in the signal chain - greatly affecting both accuracy and power consumption. ROHM is developing op amps that satisfy the dual need for high accuracy and low current consumption. By further refining the circuit design based on original Nano Energy™ technology, ROHM is now able to offer an op amp that delivers the lowest current consumption on the market.
The LMR1901YG-M leverages original ultra-low power technology that thoroughly suppresses current increase caused by temperature and voltage changes to reduce current consumption to just 160nA (Typ.) - approximately 38% lower than that of general low power op amps. This not only extends the life of applications powered by internal batteries like electronic shelf labels, but also contributes to longer operating times for smartphones and other devices equipped with rechargeable batteries. At the same time, this low current consumption does not change over the temperature range of -40°C to +105°C - allowing stable low-power operation, even in environments where external temperatures fluctuate, including fire alarms and environmental sensors.
Other performance enhancements include 45% reduction of input offset voltage to just 0.55mV (Max. Ta=25°C) over general low-current op amps while a maximum input offset voltage temperature drift of 7V/°C is guaranteed. This enabling high accuracy amplification of sensor signals. Capable of operating from 1.7V to 5.5V supply voltage and offering rail-to-rail input/output, LMR1901YG-M is suitable for a wide variety of applications in the industrial equipment and consumer markets. ROHM’s new op amp also complies with the automotive reliability standard AEC-Q100 - ensuring stable operation even under harsh conditions such as vehicle cabins without compromising functionality.
In addition to various technical documents necessary for circuit design and SPICE models for simulation (available free of charge on ROHM’s website), the LMR1901YG-M can be used with ROHM Solution Simulator to speed up time to market.
Going forward, ROHM will continue to pursue further power savings in op amps using proprietary ultra-low power technology. On top, ROHM aims to improve the performance of op amp lineups by reducing noise and offset - increasing power savings and expanding the power supply voltage range while contributing to solving social issues through higher accuracy application control.

What is Nano Energy™ Technology?
Nano Energy™ refers to proprietary ultra-low current consumption technology that achieves a current consumption on the order of nano ampere (nA) by combining advanced analog technologies covering circuit design, layout, and processes utilizing ROHM’s vertically integrated production system.
This contributes to not only extending the operating time of battery operated IoT and mobile devices but also improving efficiency in industrial and automotive equipment where increased power consumption is problematic.

ROHM Develops the Industry‘s Smallest CMOS Op Amp Optimized for Smartphones and Compact IoT Devices
ROHM has developed an ultra-compact 1.8V - 5V, rail-to-rail CMOS operational amplifier - the TLR377GYZ. It is optimized for amplifying signals from sensors such as temperature, pressure, flow rate, used in smartphones, small IoT devices, and similar applications.
【IC】ROHM开发出静态电流仅160nA的线性运算放大器LMR1901YG-M，有助于消费电子和工业设备应用更加省电
ROHM开发出静态电流超低的线性运算放大器“LMR1901YG-M”，采用ROHM自有的超低静态电流技术，彻底抑制了因温度和电压变化而导致的电流增加问题，与普通的低静态电流运算放大器相比，静态电流减少约38%。新产品产品非常适用于传感器信号放大用途。
ROHM Introduces New BD77502FVM 2-Channel High-Speed Ground Sense CMOS Op Amp
ROHM introduces the availability of a 2 channel high-speed ground sense CMOS op amp(operational amplifier), BD77502FVM, optimized for consumer and industrial equipment requiring high-speed sensing – such as industrial measurement and control systems. The newest BD77502FVM integrates two op amp devices that prevent oscillation (i.e. due to wiring) while providing high-speed amplification with slew rates up to 10V/µs and breakthrough immunity to electromagnetic interference (EMI).
