TOKYO—Toshiba Corporation’s (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the launch of “TC75S67TU,” a new operational amplifier that realizes industry-leading[1] low noise. Sample shipments start today with mass production scheduled for August.

With the expansion of the IoT market, demand is growing for low-noise operational amplifiers to amplify the small signals detected by sensors[2]. Toshiba’s new IC optimizes process to realize industry-leading low equivalent input noise voltage, and is suited for analog front-end (AFE) circuits of sensors. Also, the new IC secures low bias current by adopting CMOS process, which helps to extend[3] operating times of batteries for small IoT devices.
