Four independent channels in a single 14-TSSOP package, each drawing 1.4 mA supply current. The JFET input stage delivers 20 pA input bias current, making this part a strong fit for high-impedance sensor conditioning, active filters, and audio signal chains where input offset drift matters. ## Dynamic performance — 4 MHz GBW, 16 V/µs slew Gain-bandwidth product is 4 MHz with a slew rate of 16 V/µs. These numbers set the usable bandwidth for a given closed-loop gain: at a gain of 10 the small-signal bandwidth is roughly 400 kHz, and the full-power bandwidth before slew limiting is about 250 kHz at 10 V output swing. The 40 mA per-channel output current can drive modest loads like a 600 Ω audio line or a 10-bit ADC input without an external buffer. Operates from a single supply of 6 V to 36 V, or split supplies.","metaTitle":"TL084BCPT JFET Quad Op-Amp, 4 MHz, 16 V/µs, AEC-Q100","metaDescription":"STMicroelectronics TL084BCPT JFET quad op-amp: 4 MHz GBW, 16 V/µs slew rate, AEC-Q100 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"16V/µs","Output Type":"-","Mounting Type":"Surface Mount","Amplifier Type":"J-FET","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Supply":"1.4mA (x4 Channels)","Number of Circuits":"4","Base Product Number":"TL084","Current - Input Bias":"20 pA","Operating Temperature":"0°C~70°C","Gain Bandwidth Product":"4 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"14-TSSOP","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"6 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2ca8b8d7fbdbd3087f5b1b07ce34cfff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL084BCPT/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for TL084BCPT?","answer":"The closest pin-compatible replacement is the standard TL084 series in 14-TSSOP, such as the TL084CDT (commercial temp) or TL084IDT (industrial temp). Both share the same JFET quad architecture, 14-TSSOP footprint, and similar 4 MHz GBW / 16 V/µs slew. The difference is the automotive AEC-Q100 qualification on the BC suffix — the standard variants do not carry that grade.
