Product details
Overview
LTC6253HTS8#TRMPBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, high-speed operational amplifier optimized for low-voltage, high-bandwidth signal conditioning. It delivers 720MHz gain-bandwidth product, 280V/µs slew rate, and 2.75nV/√Hz input voltage noise at just 3.5mA supply current per amplifier, operating from 2.5V to 5.25V supplies. Its –40°C to 125°C temperature rating and integrated shutdown pin make it suitable for precision ADC driver and battery-powered instrumentation applications.
For engineers reviewing the LTC6253HTS8#TRMPBF datasheet, LTC6253HTS8#TRMPBF pinout, LTC6253HTS8#TRMPBF application, or LTC6253HTS8#TRMPBF equivalent, key selection criteria include guaranteed high-temperature performance, rail-to-rail I/O swing with 90mA output drive, fast 3.5µs turn-on time in shutdown mode, and verified 400MHz –3dB bandwidth at unity gain into 1kΩ load.
Technical Context
The LTC6253HTS8#TRMPBF employs a dual-input-stage architecture-PNP-based for VCM = V– to ~V+ – 1.2V and NPN-based for the upper 1.2V range-enabling true rail-to-rail common-mode operation. This design maintains low input offset voltage (≤350µV typ. PNP mode) and stable CMRR (105dB) across its full input range.
Its unity-gain stable topology supports high-frequency closed-loop configurations without external compensation. The internal shutdown control asserts at VSHDN ≤ 0.8V, reducing quiescent current to 42µA while preserving fast recovery (tON = 3.5µs), making it ideal for power-cycled sensor front-ends and portable data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 720MHz - Enables stable unity-gain amplification up to 400MHz, critical for driving wideband ADCs like LTC2393-16. |
| Slew Rate | 280V/µs - Supports clean 2V step response in <36ns, minimizing distortion in fast transient signal paths. |
| Input Voltage Noise | 2.75nV/√Hz @ 1MHz - Low-noise performance preserves SNR in precision analog front-ends. |
| Supply Current per Amp | 3.5mA max @ 5V - Enables dual-channel high-speed amplification within tight power budgets. |
| Operating Temperature | –40°C to 125°C - Fully specified for automotive under-hood and industrial control environments. |
| Output Drive | ±90mA - Sustains rail-to-rail swing into 100Ω loads, eliminating need for external buffers in DAC/ADC interfaces. |
| Shutdown Current | 42µA - Reduces system standby power by >98% versus active mode, enabling energy-efficient duty cycling. |
Pinout & Package
Package: 8-Lead Plastic TSOT-23 (TS8), 3mm × 1.8mm footprint, exposed pad not present (unlike DFN variants). RoHS-compliant, lead-free finish (LTFRY marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT A | Amplifier A output | Capable of rail-to-rail sourcing/sinking up to ±90mA; connects directly to ADC input or filter network. |
| 2 –IN A | Inverting input A | High-impedance node (7.2kΩ diff, 3MΩ cm); accepts signals from V– to V+ with matched offset voltage. |
| 3 +IN A | Non-inverting input A | Same rail-to-rail common-mode range as –IN A; used for unity-gain buffer or non-inverting gain stages. |
| 4 V+ | Positive supply | Accepts 2.5V–5.25V; must be decoupled locally with 0.1µF + 10µF capacitors per amplifier section. |
| 5 +IN B | Non-inverting input B | Independent channel input; enables dual-path signal processing (e.g., differential driver or dual-sensor conditioning). |
| 6 –IN B | Inverting input B | Matched to –IN A for channel-to-channel tracking; DVOS ≤ ±350µV ensures balanced gain accuracy. |
| 7 OUT B | Amplifier B output | Electrically identical to OUT A; supports independent load driving or feedback configuration. |
| 8 V– | Negative supply / ground reference | Typically 0V; supports split-supply operation if V+–V– remains 2.5V–5.25V. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum operating junction temperature for the LTC6253HTS8#TRMPBF?
The LTC6253HTS8#TRMPBF has a maximum junction temperature (TJMAX) of 150°C, with thermal resistance θJA = 195°C/W for the TSOT-23 package. This rating supports reliable operation in under-hood automotive and industrial control environments when mounted on standard FR4 PCBs with minimal copper pour.
Does the LTC6253HTS8#TRMPBF include a shutdown pin?
No, the LTC6253HTS8#TRMPBF in the 8-lead TSOT-23 (TS8) package does not include a shutdown pin. Shutdown functionality is only available on MS10 and MS8 packages (e.g., LTC6253HMS8#TRPBF). The TS8 variant provides dual op amp functionality only, with pins 1–8 assigned strictly to OUT A, –IN A, +IN A, V+, +IN B, –IN B, OUT B, and V–.
What is the typical input offset voltage for the LTC6253HTS8#TRMPBF at room temperature?
The typical input offset voltage for the LTC6253HTS8#TRMPBF is ≤100µV at 25°C with VCM = VS/2 and VS = 5V. The maximum specified value is ±350µV across the full –40°C to 125°C temperature range, verified per the manufacturer's electrical characteristics table.
Can the LTC6253HTS8#TRMPBF drive a 100Ω load while maintaining rail-to-rail output swing?
Yes, the LTC6253HTS8#TRMPBF can drive a 100Ω load with rail-to-rail capability: VOH (V+ – VOUT) is ≤210mV and VOL (VOUT – V–) is ≤320mV at ISOURCE = 25mA and ISINK = 25mA respectively, ensuring usable swing within 320mV of either rail - sufficient for most 5V ADC input ranges and active filter implementations.
Is the LTC6253HTS8#TRMPBF pin-compatible with other members of the LTC6252/LTC6253/LTC6254 family?
The LTC6253HTS8#TRMPBF shares identical pinout with other TS8-packaged variants (e.g., LTC6253ITS8#TRMPBF), but is not pin-compatible with MSOP-8 (MS8), DFN-8 (DC), or MSOP-10 versions due to differing pin assignments - especially absence of SHDN in TS8. Always verify package-specific pin diagrams before PCB layout.
