Operational amplifiers are used in many configurations and with many variations on specifications, depending upon the application. However, an IC package of operational amplifiers will often come with several in a package (e.g., a “quad pack” will have four op amps). If you have leftover, unused op amps on the same chip, the unused ones […]

Electrostatic discharge and analog circuits: Preventing the undetectable disaster
Analog circuits are exposed to outside influences most often through input channels by way of op amps acting as filters, buffers, or amplifiers. Electrostatic discharge (ESD) results from the direct contact of two things that are at different voltage potential levels and can also be defined as a fast, high current transfer. Analog circuit exposure […]
Automotive-specific Class-D audio amplifier eliminates up to 18 external components
Texas Instruments today introduced the first 2.1-MHz Class-D audio amplifier specifically designed for automotive applications. Supporting high-resolution 96-kHz digital input, the compact TAS6424-Q1 enables high-fidelity audio with low distortion in automotive infotainment applications. The TAS6424-Q1 enables the use of smaller external filters and eliminates up to 18 external components to reduce system size and cost […]
Measuring the linear operating region of instrumentation amplifiers
by Peter Semig and Collin Wells, Texas Instruments There are numerous publications from the past two years that discuss the theoretical linear operating region of instrumentation amplifiers. The publications cover the three primary topologies of instrumentation amplifiers: three-op-amp,[1] twoop-amp,[2] and two-op-amp with gain stage,[3] which are shown in Figure 1. Each publication derives the node […]
Precision nanopower op amps excel at battery, sensor apps
Texas Instruments today introduced the industry’s first precision nanopower operational amplifiers (op amps). The LPV811 and LPV812 consume quiescent current as low as 320 nA and are part of a family of four new ultra-low-power op amps. With up to 60 percent lower power consumption than competitive precision op amps and offset voltage as low […]
