What is unipolar to bipolar converter?
Description. The Unipolar to Bipolar Converter block maps the unipolar input signal to a bipolar output signal. If the input consists of integers between 0 and M-1, where M is the M-ary number parameter, then the output consists of integers between -(M-1) and M-1. If M is even, then the output is odd.
What is unipolar output?
Unipolar signals swing from zero to positive full-scale, thus having only a positive polarity. With the single-ended analog input of an ADC, the input ranges from zero-scale (typically ground) to full-scale (typically the reference voltage).
How to make a bipolar output from a unipolar DAC?
We show you how to make a bipolar output from a unipolar DAC by adding a high-voltage op amp. A simple bipolar output circuit is shown in Figure 2. It contains a unipolar DAC, a precision voltage reference, and a precision op amp.
What kind of voltage does a max5322 DAC have?
The MAX5322 dual, 12-bit, serial-interface, digital-to-analog converter (DAC) provides bipolar ±5V to ±10V outputs from ±12V to ±15V analog power-supply voltages, or unipolar 5V to 10V outputs from a single 12V to 15V analog power-supply voltage.
How to design a unipolar to bipolar converter?
The final schematic of the unipolar to bipolar converter is the circuit in Figure 1. The math solution is a system of two equations with two unknowns. Starting with the design specifications we wrote earlier, the transfer function of the differential amplifier is written for both extremes of the output range: Solving is simple.
How does a unipolar to bipolar signal conditioning circuit work?
This unipolar to bipolar signal conditioning circuit uses an op amp with negative feedback and three resistors in a modified summing amplifier configuration to generate high-voltage bipolar outputs from a generic single supply unipolar digital-to-analog converter (DAC).
