ISL21007DFB825Z-TK

Product Overview

The ISL21007DFB825Z-TK from Intersil is a fixed-output series voltage reference in an 8-SOIC surface-mount package. It provides a 2.5V reference output with ±0.16% tolerance and a 10ppm/°C temperature coefficient, supporting a 5mA output current. The device operates from a 2.7V to 5.5V input and draws 150µA of supply current. Its 0.1Hz to 10Hz noise is 4.5µVp-p, and the operating temperature range is -40°C to 125°C (TA). This reference provides a fixed 2.5V output for board-level analog and power-management circuits.

Key Features

• Fixed 2.5V output with ±0.16% tolerance.
• 10ppm/°C temperature coefficient over the -40°C to 125°C (TA) operating range.
• 5mA output current.
• 2.7V to 5.5V input range with 150µA supply current.
• 4.5µVp-p noise from 0.1Hz to 10Hz.
• 8-SOIC (0.154 in, 3.90 mm width) surface-mount package.

Applications

• Analog-to-digital converter reference input.
• Digital-to-analog converter reference or excitation rail.
• Power-management circuit biasing or setpoint generation.
• Sensor signal conditioning front ends using a fixed 2.5V reference.
• Battery-powered control boards with limited supply current.

Design & Procurement Notes

Designers should verify that the 2.7V to 5.5V input range matches the available supply and that the 5mA output current meets the load requirement. The ±0.16% tolerance, 10ppm/°C coefficient, and 4.5µVp-p 0.1Hz to 10Hz noise can be used to estimate reference accuracy and noise contribution in ADC, DAC, and sensor-conditioning paths. The 150µA supply current is relevant for power-budget calculations, while the -40°C to 125°C (TA) range defines the specified operating envelope. The 8-SOIC surface-mount package should be checked against PCB land-pattern and clearance requirements. Procurement should confirm the exact Intersil part number ISL21007DFB825Z-TK to ensure the specified voltage, tolerance, and package are matched.
