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 […]

Then click the “Read more” link and follow the conversation on EDAboard.com or log in to EDAboard and participate in the analog IC forum threads.) Making gain positive and NF less than 7.0 dB – I have designed a mm-wave amplifier, as I intend to […]
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 […]
Wideband RF PLLs boast integrated voltage-controlled oscillators
Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry’s highest-performance phase-locked loops (PLLs) with integrated voltage-controlled oscillators (VCOs). Delivering the lowest phase-noise performance in the industry, the LMX2582 and LMX2592’s single-chip architecture helps designers achieve a level of performance previously possible only through several discrete devices. These new wideband devices support output frequencies of up […]

Delivering the lowest phase-noise performance in the industry, the LMX2582 and LMX2592’s single-chip architecture helps designers achieve a level of performance previously possible only through several discrete devices. These new wideband devices support output frequencies of up to […]
Audio op amp puts out 150 mW
Texas Instruments introduced an audio operational amplifier (op amp) that sets the latest standard in audio performance. The OPA1622 is the newest addition to the company’s Burr-Brown™ Audio line and is the next generation of the widely adopted OPA1612. The new OPA1622 delivers high output power of up to 150 mW and extremely low distortion […]
Oscillator optimized for signal integrity in performance-critical applications
Texas Instruments (TI) (NASDAQ: TXN) today introduced a family of fully programmable, pin-selectable and fixed-frequency 7-mm-by-5-mm differential oscillators that provides the industry’s lowest jitter of 90 femtoseconds (fs), which enables designers to optimize signal integrity and reduce data-transmission errors in performance-critical applications. The LMK61xx family enables easy customization, frequency margining and support for multiple frequencies […]
