STMicroelectronics TS985 rail-to-rail comparator

Click2Contact

Squeezed in a footprint smaller than 1 mm², STMicroelectronics’ TS985 comparator combines battery-friendly micropower performance with enhanced dynamic range and high speed. The 0.8 x 1.2 x 0.52 mm chip-scale package (CSP) makes the device suitable for space-constrained applications such as smartphones, smart watches, digital cameras, Internet of Things (IoT) devices and portable test equipment.

The product can operate from a supply voltage from 1.8 to 5 V, allowing use in systems powered from a single cell or generally designed to operate from low voltages to save overall power consumption. Typical operating current of 14 µA also helps minimise drain on the battery. High-speed performance is assured, as typical propagation delay of 300 ns ensures rapid response to fast-changing analog signals.

Through its rail-to-rail input, the unit accepts signal amplitudes up to the supply voltage. This enables designers to take full advantage of the limited dynamic range when operating from a low voltage and so create portable systems that deliver quality performance and features. Other features include 400 µm ball pitch, push-pull output and high ESD tolerance of 2 kV HBM/200 V MM.
