ADS7804PB

Analog To Digital Converters (ADC) Overview

The ADS7804PB is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features four single-ended input channels and operates with a maximum sampling rate of 200 kSPS. The device utilizes a standard SPI-compatible serial interface for data transfer. It functions within an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.65 V to 5.25 V. The component is housed in a 28-pin Plastic Dual In-Line Package (PDIP).

Analog To Digital Converters (ADC) Feature Summary

• Four-channel multiplexed input architecture for multi-point signal acquisition.
• Successive approximation register conversion topology ensuring low power consumption.
• Flexible dual-supply operation supporting mixed-voltage logic interfaces.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems.
• Industrial process control data acquisition modules.
• Medical equipment requiring isolated signal measurement.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package designation matches the required 28-pin DIP form factor. Confirm that the suffix 'P' corresponds to the specific plastic DIP variant intended for through-hole mounting. Ensure the operating temperature range aligns with the system's environmental requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate-speed, low-power solution with multiple inputs is required. It is suitable for applications where 12-bit resolution is sufficient and direct SPI connectivity is preferred over parallel interfaces. Consider power supply constraints as the digital and analog supplies may differ.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS780x family of low-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7805 but differs in channel count and pin configuration. The series is designed for cost-sensitive embedded systems requiring reliable analog-to-digital conversion capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Verify compatibility with ADS7804 variants having different suffixes or packages. Cross-reference specifications carefully if substituting with devices from other manufacturers offering similar SAR architectures.
