Data Acquisition – ADCs/DACs – Special Purpose is the category that TLP7830 belongs to. This specialized data converter is designed to convert an analog voltage or current input into a digital signal of either standard binary or two’s complement format.

More specifically, the TLP7830 is a low-power 8-bit Analog-to-Digital (ADC) or Digital-to-Analog (DAC) converter. As an analog-to-digital converter, it can convert a bipolar input voltage (ranging between -Vref and +Vref) into a 8-bit digital code. As a digital-to-analog converter, it can convert an 8-bit digital code into a bipolar output voltage. Additionally, this device also provides a 0.8-V (typical) reference voltage.

The most important features of the TLP7830 are its low power consumption and small package size. Additionally, its wide operating temperature range makes it suitable for harsh industrial and military applications. The TLP7830 is available as an 8-Pin mini-flat package and operates in the temperature range of 0 – 70˚C.

The TLP7830 is designed to meet the specifications of MIL-STD-1553b and ARINC429. For MIL-STD-1553b, the TLP7830 offers a high degree of linearity over the full operating range and maintains tight data integrity for bidirectional data acquisition and transmission. For ARINC429 applications, the chip maintains tight timing requirements, allowing for the accurate transmission of encoded data.

In terms of applications, this data converter is ideally suited for data acquisition, data transmission, and control systems. The converter can be used, for example, in aircraft on-board communication systems, embedded control systems, laser guidance systems, missile control systems, and other high-end instruments. Its small size and low power consumption make it an ideal choice for aircraft mounting and embedded system applications.

In order to function, the TLP7830 requires a positive and negative reference voltage in order to convert analog signals into digital codes. This reference voltage can be provided internally or externally. If the reference voltage is provided externally, the TLP7830 must be coupled to an integrated reference circuit in order to ensure high precision operation.

Once the appropriate reference voltage is provided, the TLP7830 is set up to convert analog signals into digital signals. This is accomplished by applying the signal to the TLP7830’s input pins and the desired output signal is obtained in the form of an 8-bit digital signal. For example, when used as an analog-to-digital converter, a signal ranging from -Vref to +Vref is applied to the input pins and a corresponding 8-bit digital output is obtained from the output pins.

When used as a digital-to-analog converter, an 8-bit digital code is applied to the input pins of the TLP7830, and a corresponding analog output is obtained from the output pins ranging from -Vref to +Vref. Additionally, this converter also offers a “power-on reset” feature, which allows it to reset to a preset value when power is cycled. This feature is particularly useful in the case of embedded systems, where the TLP7830-controlled circuits may be occasionally reset.

In conclusion, the TLP7830 is a highly specialized data acquisition device designed for digital and analog signal conversion in a variety of challenging environments. Due to its small size, low power consumption, wide operating temperature range, and high accuracy, this data converter is perfect for use in aircraft on-board communication systems, embedded control systems, laser guidance systems, and missile control systems.
