Product details
Overview
LTC6253IMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, unity-gain stable operational amplifier optimized for high-speed, low-power signal conditioning. It delivers 720MHz gain-bandwidth product, 280V/µs slew rate, 2.75nV/√Hz input voltage noise, 3.5mA supply current per amplifier, and operates from 2.5V to 5.25V supplies. It is widely used as an ADC driver in precision data acquisition systems such as the LTC2393-16 16-bit converter.
For engineers reviewing the LTC6253IMS8#TRPBF datasheet, LTC6253IMS8#TRPBF pinout, LTC6253IMS8#TRPBF application, or LTC6253IMS8#TRPBF equivalent, key selection criteria include its shutdown capability (42µA disable current), rail-to-rail output swing (±25mV from rails at 5mA), –40°C to 85°C industrial temperature range, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LTC6253IMS8#TRPBF 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. Its fully differential output stage supports ±90mA drive capability and fast recovery from overdrive.
It features active shutdown control (SHDN pin, logic-low active), with turn-on/off times of 3.5µs/2µs, and maintains stability under capacitive loads when series output resistance is applied. The device is specified across supply voltages of 2.7V and 5.0V, with performance validated at both extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 720MHz - enables stable unity-gain operation up to 400MHz closed-loop bandwidth for high-fidelity signal amplification. |
| Slew Rate | 280V/µs - supports clean 4V step response in <36ns, critical for driving fast ADC inputs without distortion. | Input Voltage Noise | 2.75nV/√Hz at 1MHz - preserves SNR in low-amplitude, wideband sensor or IF signal chains. |
| Supply Current per Amp | 3.5mA max - allows dual-channel high-speed amplification within tight power budgets (e.g., battery-powered instrumentation). |
| Input Common-Mode Range | V– to V+ - accepts signals spanning full supply, eliminating level-shifting needs in single-supply systems. |
| Output Swing | Rail-to-rail - delivers >4.9Vpp output from 5V supply, maximizing dynamic range into ADC reference buffers. |
| Shutdown Current | 42µA - reduces system standby power by >98% while retaining fast wake-up (<4µs) for duty-cycled applications. |
Pinout & Package
Package: 8-Lead Plastic MSOP (MS8), 3mm × 3mm body, 0.65mm pitch, exposed pad connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT A | Amplifier A output | Capable of sourcing/sinking ±90mA; rail-to-rail swing ensures full-scale drive into 1kΩ loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-2ARMZ | Higher supply current (10.5mA), lower noise (0.9nV/√Hz), no shutdown pin, SOIC-8 package | Better suited for ultra-low-noise, AC-coupled applications where power is not constrained | Select when SNR >98dB is required and PCB area allows SOIC footprint; avoid if shutdown or MSOP-8 is mandatory. |

FAQ
What is the maximum supply voltage for the LTC6253IMS8#TRPBF?
The LTC6253IMS8#TRPBF has an absolute maximum total supply voltage (V+ – V–) of 5.5V, with recommended operating range from 2.5V to 5.25V. Operation at 5.25V is fully characterized and supported across the –40°C to 85°C temperature range, ensuring reliable performance in 5V industrial systems.
Does the LTC6253IMS8#TRPBF support true rail-to-rail input and output?
Yes, the LTC6253IMS8#TRPBF supports true rail-to-rail input (VCM = V– to V+) and rail-to-rail output (VOUT = V– to V+). Its dual-input-stage architecture (PNP + NPN) enables seamless transition across the full common-mode range, and output stage delivers <25mV saturation voltage at 5mA load-verified in both 2.7V and 5V supply conditions.
What is the shutdown behavior of the LTC6253IMS8#TRPBF?
The LTC6253IMS8#TRPBF features an active-low SHDN pin (Pin 5 in MS8 package). When pulled below 0.8V, it disables both amplifiers and reduces total supply current to 42µA typical. Turn-off time is 2µs and turn-on time is 3.5µs, enabling rapid power cycling in duty-cycled systems without compromising signal integrity.
Can the LTC6253IMS8#TRPBF drive heavy capacitive loads?
The LTC6253IMS8#TRPBF is not unity-gain stable into purely capacitive loads. For loads >100pF, a series resistor (e.g., 10–50Ω) between the output and capacitive node is required to maintain stability and prevent peaking-per Figure 36/37 in the datasheet. This design practice preserves 0.1% settling time and harmonic distortion performance in ADC driver applications.
What is the input offset voltage specification for the LTC6253IMS8#TRPBF?
The LTC6253IMS8#TRPBF has a maximum input offset voltage of ±350µV at VCM = VS/2 and 25°C, with typical value <±100µV. Over the full –40°C to 85°C range, VOS drift is ±3.5µV/°C max. Channel-to-channel offset match is ±350µV max, supporting precision differential gain configurations without trimming.
