.. that produce equal voltage outputs of opposite polarity, are even more so. Figure 1’s version of a symmetrical 0 V to 10 V, 1.5 A lab supply implements an extra handy trick: computer programming via a single PWM output. Figure 1. LM337 , ...
.. Nevertheless, significant crossover distortion can be expected to creep in for low signal amplitudes and frequencies above 10 kHz or so. Design equations are unchanged from Figure 2. Materials on the topic Datasheet Microchip MCP4131 Datasheet ...
.. addition of this GaN FET adds only 15 mΩ to the switch resistance of ADP1611 (0.23 Ω) an increase of less than 10%. Please note, the gate-source voltage (V GS ) of EPC2051 cannot exceed +6 V, so be careful. Materials on the topic ...
.. challenge (see the Figure 1). It’s inexpensive and delivers an output voltage with a tempco that can be adjusted from 10 to +10 mV/ C for the values shown in the diagram. Figure 1. Almost any tempco, whether it be positive, negative, or ...
.. 39 C for R1 = 31.2k. Asterisked Rs should be precision types (1% or better). The R2 R3 D5 D6 network drives Q1 in the magic 10:1 current ratio ∆V BE measurement cycle described by Williams. Note that the absolute currents supplied to Q1 are no ...
.. the temperature of intersection (T INT ) is 58.55 C. Since the LM19 and LM61 essentially do not sink current (less than 10 µA), V OUT will be equal to whichever device has the higher output voltage. This results in a V-shaped output ...
.. 1. LM337 joins forces with 4053 CMOS switch to make a macho PWM DAC. Metal gate CMOS SPDT switches U1a and U1b accept a 10-kHz PWM 5v signal to generate a +1.25 V to 8.75 V “ADJ” control signal for the U2 regulator. ADJ = +1.25 ...

.. frequency, which is approximately 200 kHz. The maximum practical operating frequency is limited to around 500 kHz (C 1 = 10 pF, R 6 = 5.6 kΩ), where the relationship between V I and the duty cycle starts to become noticeably nonlinear. ...
.. filtering from ~20 Hz is now needed to give white noise within the audio spectrum and at a level of just greater than 10 dBu. A new and improved pink noise network Pink noise is a little trickier and needs a more complex filter to give ...
