PCA9691TS/1,118

ADCs/DACs - Special Purpose Overview

The PCA9691TS/1,118 is an 8-bit CMOS data acquisition device manufactured by NXP Semiconductors. It integrates four analog inputs, one analog output, and a serial I2C-bus interface within a TSSOP16 package (SOT403-1). The device supports single-ended or differential input configurations and utilizes successive approximation for A/D conversion. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a maximum I2C bus frequency of 1 MHz (Fast-mode Plus). Addressing is configured via three hardware pins, allowing up to 64 devices on the same bus.

ADCs/DACs - Special Purpose Feature Summary

• 8-bit successive approximation A/D conversion with on-chip sample and hold
• Four analog inputs programmable as single-ended or differential
• Multiplying Digital-to-Analog Converter (DAC) with one analog output
• Supports Fast-mode Plus (Fm+) I2C-bus at frequencies up to 1 MHz

ADCs/DACs - Special Purpose Applications

• Data acquisition systems requiring low power consumption
• Industrial process control monitoring
• Battery-powered instrumentation
• Multi-channel sensor interfaces

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper storage conditions. Check marking codes against the datasheet to ensure the correct revision. Note that availability may vary due to lifecycle status.

ADCs/DACs - Special Purpose Selection Notes

Select this variant when a TSSOP16 plastic thin shrink small outline package is required. Ensure the application supports I2C communication protocols. Verify that the supply voltage range of 2.5 V to 5.5 V matches the system design. Consider the 8-bit resolution limits for precision requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCA9691 family of 8-bit A/D and D/A converters. Other variants include the HVQFN16 (PCA9691BS) and SO16 (PCA9691T) packages. All variants share identical electrical characteristics and functionality, differing only in physical packaging dimensions and pin configurations.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements are limited to other PCA9691 variants with different packages (PCA9691BS, PCA9691T). Cross-family substitutes require verification of pin compatibility and electrical specifications.
