Toshiba Launches CMOS Operational Amplifier with Industry-Leading Low Noise

June 29, 2017

Toshiba Corporation

Storage & Electronic Devices Solutions Company


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.


  • Amplification of small signals from many kinds of sensors
  • IoT modules, HDD, sensor modules, Notebook PC, home appliances


  • Low-equivalent input noise voltage:
    VNI=16nV/√Hz (typ.)@f=10Hz, Rs=100Ω, Rf=100kΩ, VDD=2.5V
    VNI=6nV/√Hz (typ.)@f=1kHz, Rs=100Ω, Rf=100kΩ, VDD=2.5V
  • Low-current power supply: IDD=430μA(typ.)@VDD=2.5V
  • Low-voltage operation: VDD=2.2V to 5.5V
