TI introduces family of zero-drift, bi-directional current shunt monitors in SC70 packages
Devices improve accuracy and reduce board space
The INA210 family features a common-mode range from -0.3V to +26V, ensuring the ability to sense current, even on shorted power supplies. The inputs withstand differential inputs all the way up to the full common-mode capability. The bi-directional topology includes a reference pin for biasing the quiescent output to suit either unidirectional or bi-directional applications. The product family operates from a single +2.7 to +26 voltage supply. A low 100uA quiescent current minimizes drain in portable applications and enables shutdown by simply removing the power supply. Even with the power off, the shunt inputs withstand the full common-mode voltage.
The product family is available in a choice of five gains to address different application requirements. Tailored for very low drop current sensing are the INA210 (gain of 200), INA211 (gain of 500) and INA212 (gain of 1000). Combining low offsets and gains, the INA213 (gain of 50) and INA214 (gain of 100) are great solutions for wide dynamic range current sensing.
Availability, packaging and pricing
All members of the INA210 family are available now in a SC70-6 package from TI and its authorized distributors. The devices are priced at $0.65 in 1,000-piece quantities (suggested resale price).
TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, and online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
