Input offset voltage is 100 µV typical, which sets the DC error floor for a bridge or thermocouple amplifier without external nulling. For a 10 mV full-scale sensor, this represents a 1% error before gain — acceptable for many industrial monitors but marginal for weigh-scale or load-cell designs that demand sub-50 µV offset. Input bias current is 10 nA typical, low enough that source impedance up to 10 kΩ does not add significant voltage error (10 nA × 10 kΩ = 100 µV), but higher-impedance sources (e.g., pH probes) will see noticeable offset drift. Output drive is rated at 10 mA per channel, sufficient to drive a typical ADC input or a downstream filter stage without loading the amplifier into nonlinearity.","metaTitle":"INA126P Instrumentation Amplifier, 0.4 V/µs Slew Rate, 8-DIP","metaDescription":"Texas Instruments INA126P single-channel instrumentation amplifier, 100 µV offset, 200 kHz bandwidth, 2.7-36 V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Slew Rate":"0.4V/µs","Output Type":"-","Mounting Type":"Through Hole","-3db Bandwidth":"200 kHz","Amplifier Type":"Instrumentation","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Supply":"175µA","Number of Circuits":"1","Base Product Number":"INA126","Current - Input Bias":"10 nA","Operating Temperature":"-40°C~85°C","Voltage - Input Offset":"100 µV","Supplier Device Package":"8-PDIP","Current - Output / Channel":"10 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e2b6b92000988e624616cd9a4bb220f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA126P/alternatives.json"},"ai":{"faq":[{"question":"Is the INA126P obsolete?","answer":"Yes, the INA126P carries an obsolete lifecycle status from Texas Instruments.
