Slew rate is 4 V/µs with a -3 dB bandwidth of 1.3 MHz. For a precision instrumentation amp, this is enough bandwidth to handle 10 kHz to 50 kHz excitation frequencies in strain-gage or load-cell applications without significant gain error at the carrier frequency. Supply current is 700 µA quiescent, and the output can source or sink 15 mA per channel.","metaTitle":"INA128UA/2K5G4 Instrumentation Amplifier, 4V/µs Slew Rate","metaDescription":"Texas Instruments INA128UA/2K5G4 precision instrumentation amplifier, 1.3 MHz bandwidth, 25 µV offset, 2 nA bias, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Slew Rate":"4V/µs","Output Type":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"1.3 MHz","Amplifier Type":"Instrumentation","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Supply":"700µA","Number of Circuits":"1","Base Product Number":"INA128","Current - Input Bias":"2 nA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"25 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38ef53acfab362c1f4307adc148d9e91.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA128UA%2F2K5G4/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of the INA128UA/2K5G4?","answer":"It is a single-channel instrumentation amplifier with a 4 V/µs slew rate, 1.3 MHz bandwidth, 25 µV input offset voltage, 2 nA input bias current, 700 µA supply current, 15 mA output drive, and a supply span of 4.5 V to 36 V.
