ISL26325FVZ-T7A

Analog To Digital Converters (ADC) Overview

The ISL26325FVZ-T7A is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Renesas Electronics Corporation. It features four single-ended input channels and operates with an external reference voltage. The device supports a sampling rate of 250 kSPS and communicates via a standard SPI digital interface. It functions within an analog and digital supply voltage range of 2.7 V to 5.25 V. The component is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) with a width of 4.40 mm. It is rated for industrial operating temperatures ranging from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit SAR ADC architecture with a multiplexer for four single-ended inputs
• Supports high-speed data conversion at up to 250 kSPS using a serial peripheral interface
• Operates on a single power supply ranging from 2.7 V to 5.25 V for both analog and digital sections

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Portable instrumentation utilizing battery-powered single-supply operation
• Data acquisition modules for environmental monitoring applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix, as the T7A designation indicates tape and reel packaging. Confirm RoHS compliance status, noting that REACH regulations do not apply to this component. Check for active obsolescence notices or product change notifications regarding the manufacturing facility or labeling updates. Ensure the supplier provides valid traceability documentation for the 16-TSSOP package.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate resolution of 12 bits is sufficient for single-ended input signals. The 250 kSPS speed suits applications where channel switching overhead is acceptable. Verify that the system power budget aligns with the 2.7 V to 5.25 V supply range. Consider the 16-TSSOP footprint constraints during PCB layout design. Evaluate if the internal multiplexer simplifies the front-end circuitry compared to discrete solutions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISL2632x family of low-power, 12-bit ADCs. It shares architectural similarities with other members in the series but is distinguished by its specific pinout and input configuration. The device represents Renesas's legacy Intersil portfolio, now integrated into the broader analog signal chain offerings. It serves as a bridge between sensor outputs and digital processing units in mixed-signal environments.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible replacements within the ISL2632x family. Verify if newer Renesas ADCs offer improved performance metrics while maintaining the same package outline. Ensure any substitute supports the required 250 kSPS throughput and 12-bit resolution.
