New Product Release
In the field of precision signal processing, each technological innovation signifies a leap in performance and an expansion in applications.
Shanghai Analogy Semiconductor Technology Co., Ltd. (hereinafter referred to as "AnalogySemi"),
leveraging its deep expertise in analog and mixed-signal chip design,
today officially announces the launch of its new OPJ301x series of ultra-low
input bias current high-performance general-purpose operational amplifiers.
This series stands out with its ultra-low bias current, exceptional DC precision, and wide operating voltage range,
delivering outstanding performance in high-precision signal processing scenarios such as medical equipment,
handheld precision test devices, and automated mass production test equipment. It is suitable for various high-precision application needs.
Product Introduction
The OPJ301x series has a typical input bias current of 1.5fA at room temperature and a maximum bias current of no more than 100pA across the full temperature range,
showcasing its precision in current control. The OPJ301x series supports rail-to-rail input and output, with an extremely low input offset voltage of just 100μV at room temperature,
and features a high CMRR of 146dB. When configured as a differential amplifier,
this series provides excellent initial precision and rail-to-rail output, suitable for portable devices powered by a single supply.
The OPJ301 has a bandwidth of 2.5MHz, combined with its outstanding DC performance,
making it ideal for active filter circuits.
Under a gain of 1, the OPJ301 can stably drive capacitive loads up to 600pF.
This model is suitable for various circuit designs, offering small package sizes to reduce PCB usage area and lower design costs.
The OPJ301 packaging options include DIP-8, SOIC-8, MSOP-8, and SOT23-5; the OPJ3012 is a 2-channel version, available in DIP-8, SOIC-8, and MSOP-8 packages. All versions operate within a temperature range of -40°C to +125°C.
