Overview
The TS9004ISN16T is a low-voltage, micropower quad analog comparator from Silicon Labs' NanoWatt Analog portfolio. It features an internal 1.182V ±1% voltage reference and operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device draws a maximum quiescent current of 5.1µA and offers push-pull TTL/CMOS-compatible outputs with continuous source current capability up to 40mA. It exhibits a propagation delay of 7µs and includes a separate output ground pin for improved switching performance.
Feature Summary
- Ultra-low quiescent current consumption across all comparators and the integrated reference
- Internal precision voltage reference with high initial accuracy
- Push-pull output stage capable of sourcing significant current without crowbar glitches
- Wide input common-mode 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 'T' indicates tape and reel packaging containing 2500 units, distinct from the tube-packaged TS9004ISN16. Confirm that the component meets lead-free packaging standards as specified by the manufacturer. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.
Selection Notes
Select this component when a quad comparator with an integrated reference is required in a compact 16-pin SOIC package. It is suitable for applications demanding low power consumption and high output drive capability. Consider the input offset voltage and propagation delay specifications against system timing requirements. Verify that the supply voltage range aligns with the available power rails in the design.
Part Context
The TS9004 belongs to the NanoWatt Analog series, designed for high-performance analog integrated circuits with a focus on low power. It serves as a form-factor identical replacement for the MAX934 but with improved electrical specifications, including lower supply current and better reference accuracy. This positioning makes it ideal for space-constrained, battery-operated electronic devices requiring precise signal comparison.
Replacement Considerations
Public confirmed substitute part number: LTC1444IS#TRPBF (Analog Devices Inc.).
FAQ
How does the TS9004 handle output switching to prevent glitches?
The output stage is optimized to eliminate crowbar-current-free switching, minimizing glitches caused by parasitic feedback or suboptimal board layout during transitions.
What is the function of the separate GND pin on the TS9004?
The separate GND pin allows the output to swing from V+ to GND while the V- pin can be set to a voltage below GND, enabling TTL compatibility and bipolar-to-single-ended conversion.
