What are the key features of TLC7528CPWRG4?
- Dual independent 8-bit R-2R DAC channels with parallel 8-bit interface enable simultaneous two-channel analog output updates from a single write cycle
- Wide analog output voltage range of -10 V to +10 V supports bipolar signal generation for industrial process control and arbitrary waveform synthesis
- Multiplying architecture accepts an external reference voltage, allowing gain scaling and waveform shaping applications without additional analog multiplier ICs
What is TLC7528CPWRG4 used for?
TLC7528CPWRG4 is designed for industrial process control systems, programmable gain amplifiers, and arbitrary waveform generators where two independent 8-bit analog voltages must be updated synchronously from a parallel microcontroller bus. Its bipolar ±10 V output range directly interfaces with industrial 4–20 mA transmitter setpoint circuits and servo drive command inputs without level-shifting amplifiers. The multiplying architecture also enables digitally controlled attenuation and modulation functions in audio signal processors and function generators.

Frequently Asked Questions
How many bits of resolution does TLC7528CPWRG4 provide and what analog output range does that correspond to?
TLC7528CPWRG4 provides 8-bit resolution, giving 256 discrete output levels across an analog output voltage range of -10 V to +10 V, which corresponds to a step size of approximately 78 mV per LSB. This resolution is adequate for industrial setpoint DAC applications where 1% or better accuracy is required without the cost of higher-bit solutions.
How does the parallel interface of TLC7528CPWRG4 differ from SPI-based DACs in a microcontroller design?
TLC7528CPWRG4 uses an 8-bit parallel interface that allows both DAC channels to be updated within a single write cycle of approximately 100 ns, versus the multiple clock cycles required by an SPI DAC to shift in 8 to 16 bits serially. This makes it preferable in systems where update latency of less than 200 ns is critical, such as fast control loops in motor drives or real-time waveform synthesis.
For a bipolar servo drive command interface, how should TLC7528CPWRG4 be connected to produce a ±10 V output?
In a multiplying configuration, TLC7528CPWRG4's VREF pin is driven by a precision ±10 V reference or an op-amp buffer, and the IOUT pin feeds an external transresistance amplifier that converts the R-2R current output to a ±10 V voltage swing. This two-op-amp configuration is standard for achieving full bipolar range from the 8-bit DAC in industrial servo command circuits requiring less than 0.4% linearity error.
What is the maximum linearity error of TLC7528CPWRG4 and how does it affect a closed-loop control application?
TLC7528CPWRG4 specifies a maximum linearity error (integral nonlinearity) of 0.3906%, equivalent to approximately ±1 LSB at 8-bit resolution. In a closed-loop PID control application, this INL contributes a systematic position or speed error of up to 0.4% of full scale, which is acceptable for most industrial actuators but may require a correction lookup table in precision robotics or optical positioning stages.
