Product details
Overview
LTC6252IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input/output operational amplifier optimized for high-speed, low-power signal conditioning in 2.5V–5.25V systems. It delivers 720MHz gain-bandwidth, 280V/µs slew rate, 2.75nV/√Hz input noise, 3.5mA quiescent current, and operates across –40°C to 85°C - enabling precision ADC driving and low-voltage RF front-end buffering.
For engineers reviewing the LTC6252IS6#TRMPBF datasheet, LTC6252IS6#TRMPBF pinout, LTC6252IS6#TRMPBF application, or LTC6252IS6#TRMPBF equivalent, key selection criteria include its TSOT-23-6 package, shutdown capability (42µA), rail-to-rail swing at ±25mA output, and guaranteed performance over industrial temperature range without derating.
Technical Context
The LTC6252IS6#TRMPBF employs a dual-input-stage architecture: a PNP pair active from V– to ~1.2V below V+, and an NPN pair taking over near V+ to maintain rail-to-rail common-mode range. This design enables seamless input coverage across the full supply while preserving low offset (≤350µV typ. in PNP mode) and bias current cancellation (≤100nA typ. at mid-rail).
Its unity-gain-stable 720MHz GBW and 400MHz –3dB bandwidth are achieved with minimal phase margin degradation across 2.5V–5.25V supplies, supported by fast turn-on/turn-off times (3.5µs/2µs) on the SHDN pin and robust 90mA output drive into 1kΩ loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 720MHz - enables stable unity-gain operation up to 400MHz closed-loop bandwidth for wideband filtering or ADC driver applications. |
| Slew Rate | 280V/µs - supports clean 2V step response in ≤36ns (0.1%), critical for high-fidelity pulse amplification. |
| Input Noise Density | 2.75nV/√Hz @ 1MHz - ensures minimal added noise in low-amplitude sensor or IF signal chains. |
| Supply Current | 3.5mA max per amplifier - allows battery-powered instrumentation with multi-channel analog front-ends. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial control, automotive body electronics, and outdoor IoT sensor nodes. |
| Output Drive | ±90mA - drives 50Ω cables or 1kΩ ADC inputs directly without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARMZ | Lower noise (1nV/√Hz), higher supply current (9.5mA), no shutdown pin, MSOP-8 package | Better SNR in ultra-low-noise preamps; unsuitable for power-constrained or space-limited designs | Select when noise dominates budget and PCB area allows larger MSOP-8 footprint |
| OPA837IDBVR | Higher GBW (110MHz), lower supply current (1.2mA), no rail-to-rail output, SOT-23-6 package | Lower power for medium-bandwidth apps; cannot drive ADCs requiring full rail swing | Select when supply current is critical and output swing >95% of rail is acceptable |

FAQ
What is the maximum supply voltage for LTC6252IS6#TRMPBF?
The LTC6252IS6#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 5.5V. Its specified operating range is 2.5V to 5.25V, with full electrical performance guaranteed at 2.7V and 5.0V supplies. Exceeding 5.25V may degrade long-term reliability even if within absolute maximum ratings.
Does LTC6252IS6#TRMPBF support true rail-to-rail output swing under load?
Yes, the LTC6252IS6#TRMPBF delivers rail-to-rail output swing: at 5V supply, it swings within 65mV of V– and 120mV of V+ with 25mA sink/source current. At lighter loads (no load), swing improves to within 25mV of V– and 65mV of V+, enabling direct interface with 16-bit ADCs requiring full-scale input range.
How does the dual-input-stage architecture affect offset voltage in LTC6252IS6#TRMPBF?
The LTC6252IS6#TRMPBF uses separate PNP and NPN input stages. Offset is ≤350µV when the PNP stage is active (VCM = 0V to ~3.8V at 5V supply), but increases to ≤2.2mV in the NPN region (VCM > ~3.8V). This transition is seamless and does not cause discontinuities, but system-level offset calibration should account for the region of operation.
Can LTC6252IS6#TRMPBF drive a 50Ω coaxial cable directly?
The LTC6252IS6#TRMPBF can source/sink ≥90mA, supporting short 50Ω cable runs (<1m) at moderate frequencies. For sustained 50Ω driving above 10MHz, a series resistor (e.g., 20–50Ω) is recommended to dampen reflections and reduce overshoot, as shown in typical application Figure 36 of the datasheet.
Is the SHDN pin of LTC6252IS6#TRMPBF compatible with standard logic levels?
Yes, the SHDN pin of LTC6252IS6#TRMPBF is CMOS-compatible: it asserts shutdown when pulled ≤0.8V (VL) and enables normal operation when ≥2.0V (VH). The pin draws <300nA at 2V, allowing direct connection to microcontroller GPIOs without level-shifting or additional drive circuitry.
