Product details
Overview
LTC6262HTS8#TRPBF from Analog Devices is a dual, rail-to-rail input/output, micropower operational amplifier in an 8-lead TSOT-23 package. It delivers 30MHz gain-bandwidth, 240µA supply current per amplifier, ±10mA output drive, and operates from 1.8V to 5.25V supply - enabling precision signal conditioning in battery-powered instrumentation and automotive sensor interfaces.
For engineers reviewing the LTC6262HTS8#TRPBF datasheet, LTC6262HTS8#TRPBF pinout, LTC6262HTS8#TRPBF application, or LTC6262HTS8#TRPBF equivalent, key selection criteria include its –40°C to 125°C H-grade temperature rating, shutdown capability (≤10µA), 400µV max input offset, 100nA max input bias current, and stable operation with up to 1nF capacitive loads.
Technical Context
The LTC6262HTS8#TRPBF uses a composite PNP/NPN input stage that enables rail-to-rail common-mode input range (–0.1V to VS + 0.1V) and maintains low input bias current (≤100nA) across 0.2V–0.2V from rails. Its patented buffer and output bias architecture supports unity-gain stability with 1nF loads while delivering 7V/µs slew rate.
Shutdown control is active-low on dedicated SHDN pins per channel, with defined VIH/VIL thresholds (1.5V/0.6V at 5V supply), 15µs turn-on, and 6µs turn-off timing. The device achieves 100dB CMRR and 95dB PSRR over DC–10kHz, supporting high-accuracy measurement in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 30MHz - enables stable closed-loop gain ≥10 at 3MHz or ≥2 at 15MHz for anti-aliasing filter design. |
| Supply Current per Amplifier | 240µA - allows dual-channel operation at <500µA total, critical for multi-day battery life in portable sensors. |
| Input Offset Voltage | ±400µV max - ensures ≤0.1% error in 0.4V full-scale 12-bit ADC driver applications without trimming. |
| Rail-to-Rail I/O | VIN: –0.1V to VS+0.1V; VOUT: within 120mV of rails at 100µA load - supports true ground-sensing and single-supply 0–3.3V systems. |
| Capacitive Load Drive | Stable with ≤1nF - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial edge-node deployments. |
| Shutdown Current | ≤10µA - reduces system standby power by >98% versus active mode, enabling duty-cycled sensing. |
Pinout & Package
Package: 8-Lead Plastic TSOT-23 (2mm × 2mm × 0.8mm), exposed pad connected to V–. Thermal resistance θJA = 195°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, sinks/sources ≥10mA, high-Z in shutdown. |
| 2 | –INA | Inverting input - accepts voltage from V– – 0.1V to V+ + 0.1V; protected by back-to-back diodes. |
| 3 | +INA | Non-inverting input - identical voltage range and protection as –INA. |
| 4 | V– | Negative supply - must be connected; exposed pad soldered to PCB ground plane for thermal performance. |
| 5 | V+ | Positive supply - 1.8V to 5.25V range; bypass with 0.1µF ceramic capacitor near pin. |
| 6 | OUTB | Amplifier B output - electrically identical to OUTA; independent shutdown control. |
| 7 | –INB | Inverting input for amplifier B - fully isolated from channel A; same ESD protection. |
| 8 | +INB | Non-inverting input for amplifier B - no crosstalk with channel A inputs or outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise input stage | 13nV/√Hz voltage noise density at 1kHz - preserves SNR in front-end amplification of µV-level sensor signals. |
| Composite input topology | Seamless PNP/NPN transition across common-mode range - eliminates crossover distortion in rail-to-rail input operation. |
| Dual independent shutdown | Separate SHDN pins not present; TSOT-23 variant uses shared SHDN (pin 3 on MS8/MSOP-10 only) - LTC6262HTS8#TRPBF has no SHDN pin. |
| High PSRR/CMRR | 95dB PSRR and 100dB CMRR at DC - rejects supply ripple and common-mode interference in single-supply 3.3V systems. |
| Robust output stage | ±20mA absolute max output current - sustains 10mA continuous drive into 330Ω loads without thermal shutdown. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4522-2ARMZ | Zero-drift architecture; 3µV max VOS, 0.015µV/°C drift; 1.8MHz GBW; 440µA per amp. | Better DC precision but lower bandwidth - suitable for weigh-scale bridges, not high-speed ADC drivers. | Select ADA4522-2ARMZ when VOS drift <0.1µV/°C is required and bandwidth ≤2MHz suffices. |
| OPA2333AIDR | Zero-drift; 12µV max VOS; 350kHz GBW; 17µA per amp; 1.8V–5.5V supply. | Ultra-low power but narrow bandwidth - fits always-on environmental monitors, not dynamic signal acquisition. | Select OPA2333AIDR when sub-20µA supply current is mandatory and signal bandwidth <100kHz. |
Compared with ADA4522-2ARMZ and OPA2333AIDR, LTC6262HTS8#TRPBF uniquely balances 30MHz bandwidth, 240µA power, and –40°C to 125°C operation - making it optimal for high-fidelity, wideband, temperature-resilient sensor interfaces where zero-drift isn't required.

FAQ
Does LTC6262HTS8#TRPBF support shutdown functionality?
No, LTC6262HTS8#TRPBF does not include shutdown capability. Shutdown is only available on MSOP-10 (LTC6262HMS#TRPBF) and MSOP-8 (LTC6262HMS8#TRPBF) variants. The TSOT-23 package (LTC6262HTS8#TRPBF) omits the SHDN pin to maintain compact footprint - all eight pins are dedicated to power, inputs, and outputs for both amplifiers.
What is the maximum capacitive load LTC6262HTS8#TRPBF can drive stably?
LTC6262HTS8#TRPBF is unity-gain stable with capacitive loads up to 1nF, as verified in the datasheet's Capacitive Load Handling plot (Figure 28). This allows direct connection to ADC input capacitance (typically 10–20pF), long PCB traces (>5cm), or filtering networks without external isolation resistors or compensation.
Can LTC6262HTS8#TRPBF operate from a 1.8V single supply?
Yes, LTC6262HTS8#TRPBF is fully specified for 1.8V to 5.25V supply operation. At 1.8V, it maintains 28MHz GBW (min), 240µA supply current (typ), rail-to-rail input (–0.1V to 1.9V), and output swing within 100mV of rails at 100µA load - enabling compatibility with modern ultra-low-voltage MCUs and sensors.
What is the input voltage range specification for LTC6262HTS8#TRPBF?
LTC6262HTS8#TRPBF features rail-to-rail input with a guaranteed common-mode range of V– – 0.1V to V+ + 0.1V across –40°C to 125°C. This allows true ground-referenced signal acquisition (e.g., 0–3.3V sensor outputs) and operation with split supplies (e.g., ±0.9V), provided total supply differential remains 1.8V–5.25V.
Is LTC6262HTS8#TRPBF pin-compatible with other packages in the LTC6262 family?
No, LTC6262HTS8#TRPBF is not pin-compatible with MSOP-8 or MSOP-10 variants. The TSOT-23 package uses a unique 8-pin arrangement (OUTA, –INA, +INA, V–, V+, OUTB, –INB, +INB), whereas MSOP-8 places SHDN on pin 3 and rearranges inputs/outputs. PCB layout must be specific to the TSOT-23 footprint.
