Design an analog front end for a pH probe
pH probes, with their bipolar voltage outputs and high output impedance, need signal conditioning through an analog front end to make them compatible with measurement circuits such as A/D converters. By Marian Hryntsiv, Renesas Electronics People who work in healthcare, food and beverage, water treatment, chemical processing, agriculture, and environmental monitoring rely on pH meters […]
Dual op-amp boosts sensor signals
STMicroelectronics’ TSB182 dual operational amplifier is featured for high-accuracy signal conditioning with sensors, including maximum 20µV input offset voltage, 100nV/°C drift over temperature, and 4V-36V operating range for medium-voltage applications. In addition to its high accuracy, stability, and wide supply-voltage range, the TSB182 is specified from -40°C to 125°C. With a maximum offset voltage of 30µV over […]
Automotive, industrial op-amps operate to 175C
STMicroelectronics’ TSZ181H1 and dual TSZ182H1 automotive-qualified operational amplifiers (op amps) deliver high accuracy and stability over a wide (-40°C to 175°C) temperature range. The high maximum operating temperature encourages use in harsh environments and in applications with long mission profiles. The op amps have very low input offset voltage, typically 3.5µV at 25°Cm, and input bias current, typically 30pA […]
PC-specific audio device combines smart amplifier and low-power codec
Cirrus Logic announced today a premium audio solution built specifically for PCs that enables a louder, more immersive audio experience, whether listening to voice calls and music from the small internal speakers on ultrathin laptops or from headphones.

Zero-drift amplifiers finesse ultralow-frequency signals, Part 3
Modern zero-drift amplifiers provide the extremely low drift and noise performance, needed for processing many optical biological, and physical-world signals near 0 Hz. Contrary to what you might think, mechanical chopping is still alive and useful. Given the outstanding performance of electronic components, using a high-performance zero-drift amplifier seems the way to go. That is […]
Zero-drift amplifiers finesse ultralow-frequency signals, Part 2
Modern zero-drift amplifiers provide the extremely low drift and noise performance needed for processing many optical biological, and physical-world signals near 0 Hz. The ultimate limitations of chopping led designers to investigate another approach called auto-zeroing, which is especially feasible with integrated circuits. This is a dynamic correction technique that works by sampling and subtracting […]
Zero-drift amplifiers finesse ultralow-frequency signals, part 1
Modern zero-drift amplifiers provide the extremely low drift and noise performance needed for processing many optical biological, and physical-world signals near 0 Hz. In our world of ever-faster, wider-bandwidth signals and systems operating at higher and higher frequencies, it may seem that signals in the very-low-frequency range — down towards zero hertz (0 Hz) — […]
