ISL60002DIH312Z-TK

Overview

The ISL60002DIH312Z-TK is a precision series voltage reference IC manufactured by Renesas Electronics. It utilizes proprietary Floating Gate Analog (FGA) technology to deliver a fixed output voltage of 1.25V with an initial accuracy tolerance of ±5.0mV. The device operates within an input voltage range of 2.7V to 5.5V and draws a typical supply current of 350nA, supporting up to 900nA in some configurations. It features a temperature coefficient of 20ppm/°C and provides a maximum output current of 7mA for both sourcing and sinking. The component is housed in a surface-mount SOT-23-3 package and is rated for operation between -40°C and +85°C.

• Ensures thermal stability with a guaranteed temperature coefficient of 20ppm/°C across the operating range.

Applications

• High-resolution data acquisition systems
• Portable instrumentation and test equipment
• Battery-powered measurement devices
• Industrial control signal conditioning

Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm packaging type, as distributor listings may vary between tape-and-reel and cut-tape formats. Ensure the order includes the correct RoHS compliance status, as manufacturing updates may affect environmental declarations. Cross-reference the full part number with the latest datasheet revision to confirm pinout and electrical specifications match your design requirements before finalizing procurement.

Selection Notes

Select this component when designing circuits that require a stable, low-noise reference voltage with minimal quiescent current draw. The 1.25V output is ideal for interfacing with ADCs and DACs that utilize internal references or require precise scaling. Consider the ±5.0mV initial accuracy if tight tolerance is required without calibration. The SOT-23-3 package is suitable for space-constrained PCB layouts where surface-mount assembly is preferred over through-hole options.

Part Context

This device belongs to the ISL60002 FGA voltage reference family, which integrates floating gate memory cells to trim out initial offset and track temperature drift. Unlike traditional bandgap references, FGA technology eliminates the need for external trimming resistors or capacitors, reducing board space and component count. The family offers various fixed output voltages and accuracy grades, making it a versatile solution for precision analog front-ends in industrial and consumer electronics.

Replacement Considerations

Direct replacements include other ISL60002 variants with different output voltages such as ISL60002DIH325Z-TK (2.5V) or ISL60002DIH310Z-TK (1.024V), provided the system allows for voltage adjustment. Verify that any substitute maintains the same SOT-23-3 footprint and FGA technology characteristics to ensure compatibility with existing thermal and power management designs.
