Three new op amps bring low offset, low drift, and wide gain bandwidth for industrial designers.
In analog low-frequency circuit design, few components can be considered as integral and versatile as the operational amplifier (op amp). With a single device, designers can create amplifiers, adders, differentiators, or oscillators, all by configuring the external components. As a result, the op amp offers much utility in modern electronics, with three companies recently releasing new op amp chips for designers to leverage in next-generation applications.
STMicroelectronics, Analog Devices, and Rohm Semiconductor have released new op amps in the past few months.
While many op amps can be used interchangeably, not all op amps are created equal. This article will take a closer look at each newly-released op amp to determine how it distinguishes itself from others, what it can offer designers, and what applications it can best support.
ST Announces Low-Power, Low-Offset Amplifier
STMicroelectronics recently announced the TSZ151 series of industrial and automotive op amps. ST describes the TSZ151 (datasheet linked) as a high-accuracy amplifier with a very low input offset voltage and small temperature drift, allowing designers to amplify signals accurately without worrying about input offset modifying the output signal.

The input offset is reported to be 7 μV at 25°C, with a value below 10 μV across the entire operation range, allowing users to deploy systems to various environments without requiring extensive calibration. The typical supply current for the TSZ151 is approximately 210 μA. In addition, the gain bandwidth of 1.6 MHz places the TSZ151 between the TSZ121 and TSZ181, giving designers more choices to achieve a good balance of cost, power consumption, and performance.
The TSZ151 is targeted at industrial and automotive applications, where the high-accuracy output and low offset across the operation range can withstand harsh environments. The TSZ151 is available in sample quantities in SC70-5 and SOT23-5 packages.
ADI Releases Speedy, High-Voltage Op Amp
Analog Devices has also recently released a new high-voltage rail-to-rail op amp. The ADA4511 (datasheet linked) is a dual-channel amplifier with an input supply of up to 40 V (±20 V). Combined with the fast slew rate of 19 V/μs and wide gain bandwidth of 10.4 MHz, the ADA4511 is suitable for various applications, including data acquisition systems, industrial and medical equipment, and precision current measurement.

In addition, the Analog op amp includes multiplexer compatible inputs, meaning the ADA4511 can be used to solve many signal chain problems while giving designers more flexibility in their designs.
Rohm Unveils Low-Offset, Low-Drift Op Amp
Finishing up this roundup, Rohm Semiconductor has announced the LMR1002F low-drift, low-offset op amp. Much like the ST TSZ151, the LMR1002F (datasheet linked) features an ultra-low input offset voltage, with a maximum of 9 μV across the entire operating range and a 50 nV/°C offset drift. This is complemented by the 1.5 MHz gain bandwidth and low input noise density to craft a precise and accurate amplifier. Typical current draws for the LMR1002F are near 850 μA in the 2.7–5.5 V supply range.
