The AD7741BRZ-REEL7 is a precision PWM-controlled voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter integrated circuit (IC) for instrumentation and industrial applications. It operates from a single supply voltage ranging from 4.5 V to 18 V and provides ± 80 mV and ± 0.5% resolution, respectively. This makes it an ideal choice for applications requiring accurate and precise voltage and frequency control. Furthermore, the device features both a PWM output and a linear output, making it easy to integrate with both linear systems and PWM control systems.

The AD7741BRZ-REEL7 is designed to be used as both a voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter. It features a selector switch that allows the user to switch between these two modes. When the switch is set to the V/F mode, the IC uses the voltage on the analog input to set the frequency at the PWM output. The PWM output is proportional to the voltage input and can provide a wide range of frequencies with excellent accuracy and high stability. Conversely, when the switch is set to the F/V mode, the IC uses the frequency on the PWM input to set the voltage at the linear output. The linear output is proportional to the frequency input and can provide a large range of voltages with excellent accuracy and high stability.

The AD7741BRZ-REEL7 features a wide input voltage range of 4.5 V to 18 V and a wide output frequency range of 20 Hz to 1 MHz. Both the PWM and linear outputs are remarkably stable and accurate over the entire frequency range. It also features an adjustable voltage reference that ensures excellent accuracy over the entire frequency range. In addition, it includes a programmable gain block and a programmable offset block to precisely control the gain and offset of the PWM output.

The AD7741BRZ-REEL7 is equipped with an enable input for controlling the enable/disable state of the device. It also features digital power-up/power-down control to minimize power consumption. The IC also provides temperature monitoring of the internal circuitry to prevent thermal runaway. The device is small, power-efficient and is thermally enhanced to allow it to be mounted in very small package sizes.

The AD7741BRZ-REEL7 is suitable for a variety of both industrial and instrumentation applications. Its high accuracy and stability make it ideal for use in data acquisition systems, laboratory power supplies, precision current measurement devices, and other applications requiring precise voltage and frequency control.
