1.2 MHz GBW, 0.4 V/µs slew — signal bandwidth ceiling for sensor conditioning
The OPA170ASDRLTEP is a single-channel general-purpose op-amp from Texas Instruments, offering a gain-bandwidth product of 1.2 MHz and a slew rate of 0.4 V/µs. These parametric limits define the maximum signal frequency the amplifier can reproduce without distortion: at a gain of 10, the closed-loop bandwidth is roughly 120 kHz, and a full-scale 5 V output step slews in about 12.5 µs. The rail-to-rail output stage swings within millivolts of both supply rails, preserving dynamic range in low-voltage single-supply systems. Supply current is 110 µA typical, making it suitable for always-on sensor interfaces where quiescent power matters.
2.7 V to 36 V supply span — single-rail or split-rail flexibility
The OPA170ASDRLTEP operates from a supply span of 2.7 V minimum to 36 V maximum. This wide range covers 3.3 V and 5 V logic rails as well as 12 V and 24 V industrial supplies, and supports split supplies up to ±18 V. The input common-mode range extends to the negative rail, so the amplifier can sense ground-referenced signals without a negative bias.
-40°C to 150°C — high-temperature grade for under-hood or process control
The operating temperature range spans -40°C to 150°C, which exceeds the standard industrial -40°C to 125°C envelope. This qualifies the OPA170ASDRLTEP for engine-bay electronics, downhole instrumentation, and other high-ambient environments where the junction temperature may approach 150°C. The 250 µV typical input offset voltage and 8 pA input bias current hold across the full temperature range per the datasheet's min/max limits — not just the 25°C typical values.
SOT-553 package — 1.6 mm × 1.6 mm footprint for dense PCB layouts
The OPA170ASDRLTEP is supplied in a SOT-553 package with a supplier device package designation of SOT-5. The 5-lead, 0.5 mm pitch footprint occupies about 2.5 mm² of board area, suitable for space-constrained multi-channel arrays. The part is offered in Tape & Reel (TR) and Cut Tape (CT) options for both volume production and prototyping.
Active lifecycle, ROHS3 — no end-of-life risk for new designs
Texas Instruments lists the OPA170ASDRLTEP as Active with no NRND or EOL flags. The part is ROHS3 compliant, meeting EU Directive 2015/863 without exemptions.
