Single-ended input to differential output conversion circuit reference design

This TI Precision Verified Design provides the principles, component selection, simulation, PCB design and measurement details for a single-ended input of a specific differential output circuit that converts a single-ended input from +0.1V to +2.4V ±2.3V differential output on a single +2.7V supply. The output range is specifically limited to maximize its linearity. This circuit consists of 2 amplifiers. An amplifier acts as a buffer, creating the voltage Vout+. The second amplifier inverts the input and increases the reference voltage to produce Vout-. Both Vout+ and Vout- range from 0.1V to 2.4V. The voltage difference Vdiff is the difference between Vout+ and Vout-. This will give a differential output voltage range of +2.3V.

Analog PWM generator, 5V 500kHz PWM output

This verification design utilizes a triangle wave generator and comparator to generate a pulse-width modulated (PWM) waveform with a duty cycle that is inversely proportional to the input voltage. The op amp and comparator generate a triangular waveform, which is then passed to one input of the comparator. By passing the input voltage to the other comparator inputs, a PWM waveform is generated. Negative feedback from the PWM waveform to the error amplifier is used to ensure high accuracy and linearity of the output. This design was constructed using the OPA2365 op amp, TLV3502 comparator, and REF3325 reference. Learn more about TI's high-precision designs
