91. Designing a wideband analog voltage and current meter. Part 1
    Circuits Texas Instruments LM4562
    Design a wideband analog multimeter to measure AC voltages and currents from 20 Hz to 1 MHz with a selectable sensitivity from 1 mV to 100 V, while the ammeter has a selectable current sensitivity of 10 mA to 10 A. It may be surprising to offer a ...

92. Isolated driver forms solid-state circuit breaker
    Circuits Texas Instruments SN74HC14
    The circuit in Figure 1 allows standard TTL logic levels to safely drive a high-power dc load. The circuit provides for both signal and ground isolation as well as a solid-state circuit breaker. Figure 1. An overcurrent condition in this isolated ...

93. Circuit level-shifts ac signals
    Circuits Texas Instruments TLC071
    AC signals can emanate from many sources, and many of these sources are incompatible with the most popular interface voltages, such as TTL. A temptation always exists to capacitively couple the ac signals because capacitive coupling strips off the ...

94. My favorite design idea of all time…
    Articles Texas Instruments LM318
    The editors of EDN will tell you that the Design Ideas section is the most popular section of the website, this goes back to the print editions, where that was the first section that most if not all readers turned to first upon getting a new issue. ...

95. Set DC input-stage gain/attenuation over a 96 dB range with PWM
    Circuits Texas Instruments TLV2372
    Pulse width modulation (PWM) is a simple and inexpensive (therefore popular!) way to implement moderate performance (e.g., 8 bit resolution low speed) digital to analog conversion, but improvising cheap DACs isn’t the only thing PWM can do. ...

96. Turn a set/reset latch into an astable/monostable multivibrator
    Circuits Texas Instruments SN74HC00 SN74HC02 CD4001B CD4011B CD4013B
    This Design Idea describes a simple way to form a reliable astable or monostable multivibrator from a set/reset latch. You may find it useful because it lets you minimize the number of standard digital ICs your design requires when absolute ...

97. Squeeze extra resolution from an 8-bit DAC with Shannon decoder idea
    Articles Texas Instruments TLV2371 TLV5624
    When someone notices that two 8-bit DACs can be bought for less than one 16-bit DAC, a classic question is often asked: Why can’t you simply take two 8-bit DACs, assign one to the MSByte, the other to the LSByte, sum their outputs in a 28:1 ...

98. DAC (PWM) Controlled Triangle/Sawtooth Generator
    Circuits Texas Instruments LMC555
    Circuit designs abound for linear triangle/sawtooth generators, and many are based on the iconic LMC555 CMOS analog timer. But relatively few are voltage controlled, making them tricky to program with a DAC, and most have unbuffered outputs that ...

99. A safe adjustable regulator
    Articles Texas Instruments LM350
    Figure 1 shows a typical using of LM350 ( LM317 ) adjustable regulator when you need to adjust its output voltage. Figure 1. This voltage is approximately given here as: The potentiometer R2 is often the most unreliable part of the circuit. As ...

100. Ultra-low distortion sinewave oscillator. Part 2
     Circuits Texas Instruments LM2903 NE5532 TL072
     The sample and hold circuit (Figure 3) is considerably more complex than the oscillator. This is unfortunate but unavoidable. It's the S/H that gives this design its speed (fast settling time) and very low distortion, and it's very unlikely ...
