91. 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. ...

92. 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. ...

93. 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 ...

94. 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 ...

95. 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 ...

96. 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 ...

97. 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 ...

98. Ultra-low distortion sinewave oscillator. Part 1
    Circuits Texas Instruments LM2903 NE5532 TL072
    Introduction As discussed in the article [ 1 ], although a sinewave is the simplest possible waveform, it is also one of the hardest to generate in pure form. Any impurity represents distortion, and that means added harmonics that make very low ...

99. 90 µA Precision Voltage-to-Frequency Converter
    Circuits Texas Instruments LM334
    Figure 1 is a micropower voltage-to-frequency converter. A 0 V to 5 V input produces a 0 kHz to 10 kHz output with a linearity of 0.05%. Gain drift is 80 ppm/ C. Maximum current consumption is only 90 µA, almost 30 times lower than currently ...

100. Inverted regulator increases choice and reduces complexity
     Circuits Texas Instruments LM320 TLV2374
     Most circuits are referenced to ground, where relatively low-voltage components can monitor and control the low side of a load but not the high side. For example, nearly any low-voltage rail-to-rail-input op amp can detect a voltage increase ...
