Product details
Overview
LTC6247HTS8#TRMPBF from Analog Devices is a dual, rail-to-rail input/output operational amplifier optimized for high-speed, low-power signal conditioning in industrial and automotive systems. It delivers 180MHz gain-bandwidth product, 90V/µs slew rate, 4.2nV/√Hz input voltage noise, and operates from 2.5V to 5.25V supply with shutdown capability. It is used in precision ADC driver circuits requiring wide bandwidth and rail-to-rail swing at ≤1mA per amplifier.
For engineers reviewing the LTC6247HTS8#TRMPBF datasheet, LTC6247HTS8#TRMPBF pinout, LTC6247HTS8#TRMPBF application, or LTC6247HTS8#TRMPBF equivalent, this page provides verified electrical parameters, thermal performance across –40°C to 125°C, TSOT-23-8 package layout, and validated alternatives for low-voltage high-frequency op amp selection.
Technical Context
The LTC6247HTS8#TRMPBF employs a dual-input-stage architecture-PNP-based for VCM = V– to V+ – 1.2V and NPN-based for VCM = V+ – 1.2V to V+-enabling true rail-to-rail common-mode operation. Its unity-gain stable design supports AV = 1 configurations with 120MHz –3dB bandwidth and 74ns 0.1% settling time into 1kΩ.
It integrates active bias current cancellation for PNP inputs (IB ≤ ±350nA at 25°C), fast power-down (tOFF = 2µs, ISD = 42µA max), and robust output drive (±50mA) while maintaining CMRR ≥ 110dB and PSRR ≥ 73dB over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 180MHz - enables stable unity-gain amplification up to 120MHz closed-loop bandwidth for high-fidelity signal paths. |
| Slew Rate | 90V/µs - supports clean 2V step response with 74ns 0.1% settling, critical for fast ADC sampling clocks. |
| Input Voltage Noise | 4.2nV/√Hz @ 100kHz - preserves SNR in low-amplitude sensor and audio front-end stages. |
| Supply Current per Amp | 1mA max @ 25°C - allows dual-channel operation under 2.1mA total, ideal for battery-powered instrumentation. |
| Operating Temp Range | –40°C to 125°C - qualified for under-hood automotive and industrial control environments without derating. |
| Input Offset Voltage | ±0.5mV max - ensures <0.1% gain error in 12-bit precision measurement circuits at room temperature. |
| Output Drive | ±50mA - drives 1kΩ loads to rail with <160mV saturation, eliminating external buffers in DAC output stages. |
Pinout & Package
Package: 8-Lead Plastic TSOT-23 (TS8), 3.0mm × 1.7mm × 0.8mm profile, exposed pad not present. RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Rail-to-rail capable, sinks/sources ≥50mA, low 70mV high-side saturation at 5mA load. |
| 2: –IN A | Inverting input A | Valid from V– to V+; PNP/NPN auto-switching maintains low offset across full common-mode range. |
| 3: +IN A | Non-inverting input A | Same rail-to-rail input range as –IN A; matched offset and bias current with –IN A (ΔVOS ≤ ±0.6mV). |
| 4: V– | Negative supply | Typically 0V ground; supports negative supplies if (V+ – V–) remains 2.5V–5.25V. |
| 5: SHDN | Active-low shutdown | Pulls supply current to 42µA max when ≤0.8V; tON/tOFF = 5µs/2µs enables rapid power cycling. |
| 6: +IN B | Non-inverting input B | Independent channel; identical specs to +IN A; no crosstalk (–90dB @ 1MHz). |
| 7: –IN B | Inverting input B | Matched to +IN B; channel-to-channel VOS match ≤ ±0.6mV supports differential sensing. |
| 8: OUT B | Amplifier B output | Functionally identical to OUT A; fully independent with separate power path and no shared bias nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4807-2ARMZ | Lower 0.9nV/√Hz noise but 105MHz GBW; no shutdown pin; 2.7V–10.5V supply. | Better for ultra-low-noise precision DC-coupled sensors; unsuitable where fast power cycling or 2.5V operation is required. | Select ADA4807-2ARMZ only when noise dominates over bandwidth and shutdown is unnecessary. |
| OPA2837IDGKT | Higher 12.5mA supply current; 200MHz GBW; no rail-to-rail input; –40°C to 125°C rated. | Better for high-drive, high-bandwidth non-rail-to-rail applications (e.g., video line drivers); incompatible with single-supply sensor interfaces. | Choose OPA2837IDGKT only when output current >100mA or input common-mode range beyond rails is needed. |
Compared with ADA4807-2ARMZ and OPA2837IDGKT, the LTC6247HTS8#TRMPBF uniquely balances 180MHz bandwidth, 1mA power, rail-to-rail I/O, and integrated shutdown in an 8-pin TSOT-23-making it optimal for space-constrained, battery-sensitive, wide-dynamic-range analog front-ends.

FAQ
What is the maximum supply voltage for LTC6247HTS8#TRMPBF?
The LTC6247HTS8#TRMPBF has an absolute maximum total supply voltage (V+ – V–) of 5.5V. Its specified operating range is 2.5V to 5.25V, with full performance guaranteed at 2.7V and 5.0V supplies across –40°C to 125°C. Exceeding 5.25V may degrade long-term reliability even if within absolute maximum ratings.
Does LTC6247HTS8#TRMPBF support true rail-to-rail input at 2.5V supply?
Yes, the LTC6247HTS8#TRMPBF supports rail-to-rail input common-mode range (0V to V+) at all supply voltages from 2.5V to 5.25V. Its dual-input-stage architecture (PNP + NPN) ensures continuous operation across the full range, with input offset voltage specified at VCM = V+ – 0.5V and VCM = half-supply in the datasheet.
What is the typical output short-circuit current for LTC6247HTS8#TRMPBF?
The LTC6247HTS8#TRMPBF can source and sink up to ±100mA under absolute maximum conditions, but its typical short-circuit current is ±80mA sourcing and ±60mA sinking at 25°C with 5V supply. For sustained operation, thermal limits require heatsinking above ~50mA continuous output current.
How does the shutdown function behave on LTC6247HTS8#TRMPBF?
The SHDN pin on LTC6247HTS8#TRMPBF is active-low with logic thresholds of VIL ≤ 0.8V and VIH ≥ 2.0V. When pulled low, it disables both amplifiers and reduces total supply current to 42µA max. Turn-off time is 2µs and turn-on time is 5µs, enabling microsecond-scale power gating in burst-mode systems.
Is LTC6247HTS8#TRMPBF pin-compatible with other members of the LTC6246/LTC6247/LTC6248 family?
No-LTC6247HTS8#TRMPBF uses the 8-pin TSOT-23 (TS8) package with dedicated SHDN pin, while LTC6247 variants in MS8 or UTDFN packages have different pinouts and no SHDN functionality. Only LTC6247CTS8#TRMPBF and LTC6247ITS8#TRMPBF share identical pinout and footprint; temperature grade differs but electrical behavior is consistent.
