ISL60002BIH320Z-TK

Overview

The ISL60002BIH320Z-TK is a micropower voltage reference IC from the FGA series, manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.24%. The device operates within an input voltage range of 2.7V to 5.5V and draws a typical supply current of 350nA. It features a temperature coefficient of 20ppm/°C and supports a maximum output current of 7mA in both sourcing and sinking modes. The component is housed in a space-saving SOT-23-3 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Utilizes proprietary Floating Gate Analog (FGA) technology to achieve high precision and stability without compromising power consumption.
• Offers ultra-low supply current operation, eliminating the need for thermal stability compromises in low-power designs.
• Provides guaranteed initial accuracy options as low as ±1.0mV alongside a stable 20ppm/°C temperature coefficient.

Applications

• High-resolution, low-power data conversion systems
• Industrial controls requiring precise analog references
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix Z-TK corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status for the specific manufacturing batch. Ensure ESD handling protocols are followed due to the sensitivity of the floating gate structure. Cross-reference the exact part number against the latest Renesas datasheet to confirm pinout and electrical specifications match the design requirements.

Selection Notes

Select this component when a fixed 2.048V reference is needed with high DC accuracy and minimal quiescent current. The SOT-23-3 package is suitable for space-constrained PCB layouts. Consider the 7mA load capability for driving ADC inputs or sensor bridges. Verify that the 2.7V minimum input voltage aligns with the system's available supply rails.

Part Context

This part belongs to the ISL60002 family of micropower voltage references. The family includes various output voltages such as 1.024V, 1.25V, 2.5V, and 3.3V. All members share the same core FGA technology and SOT-23-3 packaging, differing primarily in output voltage and initial accuracy grades defined by their suffix codes.

Replacement Considerations

Direct substitutes include other ISL60002 variants with different output voltages if the circuit allows adjustment. For identical 2.048V performance, check for updated Renesas part numbers with revised suffixes. Generic bandgap references may serve as alternatives but will likely lack the specific FGA accuracy and low-noise characteristics.
