That ratio — 20 MHz GBW at 170 µA — puts it in the class of low-power signal-conditioning amps where you need bandwidth without burning the battery budget. ## Slew rate and supply current — the design decision The 26 V/µs slew rate at 170 µA per channel is the defining spec pair. For a 20 MHz GBW amp, 26 V/µs gives you enough large-signal bandwidth to drive a 2 Vpp signal to 20 MHz without slew-rate limiting. ## Package and supply — footprint and rail planning The 8-VSSOP package measures 3.00 mm x 3.00 mm body, 0.65 mm pitch — a compact dual-op-amp footprint that fits tight mixed-signal boards. No exposed thermal pad, so heat dissipation relies on the copper pour and via stitch under the device; the 20 mA per-channel output current is the practical ceiling for continuous drive into 50 Ω or 75 Ω loads. The 2.7 V floor is useful for designs running from a Li-ion cell near end-of-discharge. The 8-VSSOP package is a standard TI footprint, so supply continuity through the catalog channel is stable. If you are dual-sourcing for volume production, the closest parametric match in the same supply-and-package class is the TLV9362IDDFR — same dual-channel rail-to-rail output, 10.6 MHz GBW vs 20 MHz, 25 V/µs slew rate, and 2.6 mA supply per channel vs 170 µA. The TLV9362 draws more current but offers lower input bias (10 pA) and a wider supply range up to 5.5 V. For designs where the OPA2834's 170 µA per channel is the critical spec, there is no direct pin-compatible second source at that power level — the BOM should lock the OPA2834 as the sole source unless you can accept the higher supply current of the TLV9362.","metaTitle":"TI OPA2834IDGKT Dual Voltage-Feedback Op-Amp, 20 MHz, 26V/µs","metaDescription":"Texas Instruments OPA2834IDGKT dual voltage-feedback op-amp with 20 MHz GBW, 26 V/µs slew rate, rail-to-rail output, 170 µA per channel. 8-VSSOP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"26V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"20 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"170µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"50 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"20 MHz","Voltage - Input Offset":"350 µV","Supplier Device Package":"8-VSSOP","Current - Output / Channel":"20 mA","Voltage - Supply Span (Max)":"5.4 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.95","priceTiers":[{"qty":1,"price":"$1.95000","currency":"USD"},{"qty":10,"price":"$1.75300","currency":"USD"},{"qty":25,"price":"$1.65360","currency":"USD"},{"qty":100,"price":"$1.40890","currency":"USD"},{"qty":250,"price":"$1.32288","currency":"USD"},{"qty":500,"price":"$1.15752","currency":"USD"},{"qty":1250,"price":"$0.95909","currency":"USD"},{"qty":2500,"price":"$0.93600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b07f952bb8387d672486356df70d6a41.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA2834IDGKT/alternatives.json"},"ai":{"faq":[{"question":"Is OPA2834IDGKT obsolete or end-of-life?","answer":"No."},{"question":"How does OPA2834IDGKT compare to TLV9362IDDFR as a second source?","answer":"The TLV9362IDDFR is the closest functional peer — same dual-channel, rail-to-rail output, 8-pin package, and 25 V/µs slew rate. Key differences: TLV9362 runs 10.6 MHz GBW vs 20 MHz, draws 2.6 mA per channel vs 170 µA, and has 10 pA input bias vs 50 nA. The OPA2834 wins on power efficiency and bandwidth; the TLV9362 wins on input bias and supply range up to 5.5 V.

The 350 µV input offset and 50 nA bias suggest this is a general-purpose, low-power amp — not characterized for low-noise audio or instrumentation front-ends.
