AKM releases to production the new premium D/A converters (DACs) AK4497S and AK4498EX
Add a Schmitt-trigger function to CPLDs, FPGAs, and applications
Thanks to its internal hysteresis, the highly useful Schmitt-trigger circuit accepts a low-slew-rate input signal and produces a clean, glitch-free output transition. Unfortunately, user-programmable logic devices, such as CPLDs and FPGAs, generally offer no direct method of synthesizing Schmitt-trigger gates and buffers...
Converting pulses to a sawtooth waveform
There are multiple means of generating analog sawtooth waveforms. Here’s a method that employs a single supply voltage rail and is not finnicky about passive component values...
A short primer on X- and Y-capacitors in AC power supply
Our fundamental passive and inherently analog components – resistors, capacitors, and inductors – are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the many roles each can play in a system or circuit...
Another weird 555 ADC
Integrating ADCs that provide accurate results without requiring a precision integrator capacitor has been around for a long time. A venerable example is that multimeter favorite, the dual-slope ADC...
New high accuracy current sense amps compatible with both negative and high voltages
ROHM has developed a new lineup of high accuracy current sense amps – the BD1423xFVJ-C and the BD1422xG-C. They are qualified under the AEC-Q100 automotive reliability standard...
Three parts provide tenfold increase in switcher current
Industrial-control circuits often derive their power from widely varying sources that can exceed the 40 V maximum rating of popular switching ICs...
Circuits to help verify matched resistors
Analog designers often need matched resistors for their circuits. The best solution is to buy integrated resistor networks, but what can you do if the parts vendors do not offer the desired values or matching grade?...
Inherently DC accurate 16-bit PWM TBH DAC
The 16-bit DACs are a de facto standard for high DC accuracy and precision domain conversion, but surprisingly few are fully 16-bit (0.0015%) precise...
Push ON, push OFF for AC voltages
Stephen Woodward’s DI, “Flip ON Flop OFF” does a wonderful job for DC voltages. I thought of extending this idea to much-needed AC voltages...
