Overview
The TS9002IM8 is a low-voltage, micropower dual analog comparator in an 8-pin MSOP package. It operates from single +2.5V to +11V or dual ±1.25V to ±5.5V supplies. Key electrical parameters include a maximum quiescent current of 4µA (max) for both comparators and the reference at +25°C, rising to 5.2µa max over the -40°C to +85°C range. The device features a 7µs propagation delay with 100mV overdrive and push-pull TTL/CMOS-compatible outputs capable of continuous 40mA source current. An internal 1.182V ±0.75% voltage reference is included.
Feature Summary
- Ultra-low quiescent current consumption suitable for battery-powered systems
- Integrated 1.182V precision voltage reference with adjustable hysteresis capability
- Push-pull output stage providing high continuous source current without crowbar glitches
- Wide input common-mode voltage range extending to the negative supply rail
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific ordering suffix 'IM8' corresponds to the tube carrier format when sourcing components. Confirm that the lead-free packaging aligns with project requirements. Ensure the operating temperature range of -40°C to +85°C meets the environmental specifications of the intended application before finalizing procurement.
Selection Notes
Select this component for applications requiring low power consumption alongside precise voltage referencing. The integrated reference eliminates the need for external voltage sources, reducing bill of materials count. Consider the 8-pin MSOP package size for space-constrained designs. Verify that the 40mA output drive capability matches the load requirements of the downstream circuitry.
Part Context
The TS9002 belongs to Silicon Labs' NanoWatt Analog portfolio, designed for high-performance mixed-signal solutions. It serves as a form-factor identical replacement for the MAX923 while offering improved electrical specifications. The device is optimized for 3V and 5V single-supply applications, providing lower supply current and better initial accuracy compared to previous generations.
Replacement Considerations
The datasheet identifies the TS9002 as form-factor identical to the MAX923 analog comparator. Designers replacing the MAX923 should verify that the improved electrical specifications are compatible with existing circuit constraints.
