Renesas' op amp portfolio includes operational amplifiers that cover everything from general-purpose solutions to targeted applications like automotive. Our op amps include features like high-slew rate, high output current, and full-swing output. 

Renesas is working to expand its collection of op amps with small packages, which can reduce design size and distance to the sensor. We are also widening the range of operating temperatures (-40 to +125°C) and are developing op amp products for automotive applications that conform to AEC-Q100 standards.

1. Low power → (For Automotive) READ2351J
READ2351 is Low Power & Low Voltage Operation type.Suitable for signal processing of Portable Equipment. It can expand the dynamic range (effective range) of signal processing. It is a product which corresponds to the standard operational amplifier.
2. For high slew rate applications → (For Consumer) READ2302G (For Automotive) READ2352J
READ2302G & READ2352J are High-Slew Rate equivalent to uPC842, wideband characteristics products.
Suitable for control system and communication equipment amplifier.

Renesas will continue to expand low voltage, low noise and high input impedance line-up

Notes : Among the series UPC1251 and UPC451 , AEC-Q100 compliant products have modified a part of the chip mask pattern for products not compatible with AEC-Q100. So we change the model name as follows .

UPC1251xx(20) → UPC1251Axx(20)
PC451xx(20) → UPC451A××(20)
