The gain-bandwidth product of 14 kHz limits the usable signal bandwidth to about 2.2 kHz for a gain of 100 V/V, which is adequate for DC current monitoring, battery charging profiles, and low-speed overcurrent detection. The 0.4 V/µs slew rate sets the large-signal response time; expect a settling time on the order of tens of microseconds for a step change in shunt voltage. For applications that need to capture fast fault transients or PWM ripple above a few kilohertz, a wider-bandwidth current-sense amplifier would be a better fit. ## Package and footprint for the layout engineer The INA214BIDCKR is supplied in a 6-pin SC-70-6 package (also known as SOT-363 or 6-TSSOP). The body is roughly 2.0 mm × 1.25 mm, with a 0.65 mm pin pitch. The small footprint saves board area but demands careful decoupling — place a 0.1 µF ceramic capacitor as close as possible to the supply pin, with the ground return via directly under the pad. The device is surface-mount only; no exposed thermal pad, so the power dissipation is limited to about 200 mW at 25°C ambient, derated above that. It is ROHS3 compliant. There is no official second-source or pin-compatible replacement listed in the manufacturer's cross-reference, so dual-sourcing would require a functional equivalent from another vendor with careful validation of the pinout and gain set.","metaTitle":"INA214BIDCKR Current Sense Amplifier, Zero-Drift, SC-70-6","metaDescription":"TI INA214BIDCKR current sense amplifier, zero-drift series, 1 µV offset, 14 kHz GBW, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"Zero-Drift","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Zero-Drift","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.4V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Current Sense","Package / Case":"6-TSSOP, SC-88, SOT-363","lifecycle_stage":"eol_hot","Current - Supply":"65µA","Number of Circuits":"1","Current - Input Bias":"28 µA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"14 kHz","Voltage - Input Offset":"1 µV","Supplier Device Package":"SC-70-6","Voltage - Supply Span (Max)":"26 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.50000","currency":"USD"},{"qty":10,"price":"$1.34500","currency":"USD"},{"qty":25,"price":"$1.27640","currency":"USD"},{"qty":100,"price":"$1.04830","currency":"USD"},{"qty":250,"price":"$0.97996","currency":"USD"},{"qty":500,"price":"$0.86602","currency":"USD"},{"qty":1000,"price":"$0.68370","currency":"USD"},{"qty":3000,"price":"$0.52500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fdf0b1f5e781548adc1f9d34b3a9547d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is INA214BIDCKR a zero-drift amplifier?","answer":"Yes, it is part of the Zero-Drift series, which means the input offset voltage is chopped to a typical 1 µV and drifts very little over temperature and time."},{"question":"Can INA214BIDCKR measure bidirectional current?","answer":"The INA214BIDCKR is a unidirectional current-sense amplifier.
