GS8A015490DBT Description

The GS8A015490DBT from TT Electronics/IRC is a high-precision 8-resistor network in a 16-pin narrow SOIC package, designed for demanding isolation applications. Built with thin-film technology on a ceramic substrate, it delivers stable performance with a ±0.5% absolute tolerance and ±0.1% ratio tolerance, ensuring exceptional accuracy in signal conditioning and voltage division. The isolated (ISOL) circuit design minimizes crosstalk, making it ideal for sensitive analog and digital systems. With a 549Ω resistance value, ±100ppm/°C temperature coefficient, and 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum temperature.

GS8A015490DBT Features

• Ceramic SOIC Package: Robust rectangular form factor (9.91mm x 5.99mm x 1.45mm) with gull-wing terminals for secure surface mounting.
• Precision Performance: 0.1W (1/10) power rating per resistor (0.8W total), combined with ±0.2mm depth and ±0.1mm length/height tolerances for consistent PCB integration.
• High Reliability: Thin-film technology ensures low noise and long-term stability, while the non-automotive (PPAP: No) designation suits industrial and telecom applications.
• Wide Compatibility: EAR99 ECCN and non-RoHS status (by design) cater to legacy systems requiring durable, high-temperature operation.

GS8A015490DBT Applications

• Signal Isolation: Critical in ADC/DAC reference circuits, where precision and minimal drift are paramount.
• Voltage Division: Ideal for sensor interfaces and feedback networks in power supplies, leveraging its tight ratio tolerance.
• Industrial Electronics: Suited for test equipment, process control systems, and medical devices due to its ceramic construction and wide temperature range.
• Legacy Upgrades: A drop-in replacement for older resistor networks needing higher accuracy or better thermal performance.

Conclusion of GS8A015490DBT

The GS8A015490DBT stands out for its ceramic-based isolation, sub-1% tolerance, and thin-film stability, offering engineers a reliable solution for precision analog designs. While not RoHS-compliant, its 125°C rating and low TCR make it a robust choice for harsh environments. For applications demanding minimal crosstalk and high accuracy, this resistor network delivers superior performance over plastic-encased alternatives.
