Product details
Overview
LTC6363IMS8-2#TRPBF from Analog Devices is a precision, low-power, fixed-gain (2V/V) differential amplifier optimized as an ADC driver for 16–20-bit SAR converters. It features 7.55nV/√Hz input-referred noise, 15MHz –3dB bandwidth, rail-to-rail differential outputs, and operates from 2.8V to 11V supply. Used in battery-powered instrumentation and high-resolution data acquisition systems where gain accuracy and low distortion are critical.
For engineers reviewing the LTC6363IMS8-2#TRPBF datasheet, LTC6363IMS8-2#TRPBF pinout, LTC6363IMS8-2#TRPBF application, or LTC6363IMS8-2#TRPBF equivalent, this page delivers verified specifications, package layout, real-world use cases, and validated alternative options - all aligned with the official LTC6363-2 variant documentation and MS8 packaging.
Technical Context
The LTC6363IMS8-2#TRPBF integrates laser-trimmed on-chip resistors to deliver precise 2V/V differential gain with ≤±0.0075% gain error and ±0.5ppm/°C gain drift. Its internal architecture supports DC-coupled single-ended-to-differential conversion while maintaining 94dB minimum CMRR and 106dB CMRRI over temperature.
It employs a fully differential output stage with rail-to-rail swing, self-biased VOCM pin (4.79–5.21V at VS = 10V), and shutdown mode drawing only 70–130µA. Input common mode range extends to –2.5V at VS = 10V, enabling ground-referenced sensor interfacing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed 2V/V - eliminates external resistor matching errors and reduces board area vs discrete solutions. |
| –3dB Bandwidth | 15MHz - supports >1Msps sampling of wideband signals into SAR ADCs like LTC2378-20. |
| Input Noise Density | 7.55nV/√Hz - enables <102dB SNR in 18-bit systems with 8VP-P output swing. |
| Supply Current | 2.2mA max at 10V - balances performance and power efficiency for portable instrumentation. |
| Gain Error | ±0.0075% max - ensures <1LSB error in 20-bit systems across temperature and voltage. |
| Settling Time | 830ns to 18-bit (4ppm) - meets timing budgets for high-speed SAR ADCs with minimal dead time. |
| Input Common Mode Range | –2.5V to +10.7V at VS = 10V - accepts ground-referenced inputs without external biasing. |
Pinout & Package
Package: 8-Lead MSOP (2mm × 3mm), RoHS-compliant, exposed pad connected to V– per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting input | Differential input node; accepts single-ended or differential signals with full common-mode range support. |
| 2 (VOCM) | Output common-mode control | Sets midpoint voltage of differential outputs; self-biases to ~5V at 10V supply if left open. |
| 3 (V+) | Positive supply | Accepts 2.8V–11V; PSRR >90dB minimizes supply noise coupling to output. |
| 4 (+OUT) | Positive differential output | Rail-to-rail output capable of sourcing/sinking up to 90mA; drives ADC input directly. |
| 5 (+IN) | Non-inverting input | Paired with Pin 1 for differential input; matched input impedance (1400Ω diff) ensures balance. |
| 6 (SHDN) | Shutdown control | Logic-compatible enable; pulls supply current to ≤130µA when asserted low. |
| 7 (V–) | Negative supply | Reference for exposed pad; must be connected to PCB ground plane for thermal and electrical stability. |
| 8 (–OUT) | Negative differential output | Complementary to Pin 4; maintains tight amplitude/phase match for high SFDR performance. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed 2V/V gain | Guarantees ±0.0075% gain error and ±0.5ppm/°C drift - eliminates calibration in precision metrology. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4940-2ARMZ | Lower noise (4.5nV/√Hz), but 2.5x higher supply current (5.5mA), no integrated gain resistors. | Preferred in ultra-low-noise lab equipment; requires external gain-setting network and more board space. | Select when noise dominates budget and external precision resistors are acceptable. |
| LTC6363IMS8-1#TRPBF | Identical package and pinout; fixed 1V/V gain, 25MHz –3dB bandwidth, 10.5nV/√Hz noise. | Better suited for unity-gain buffering or applications requiring wider small-signal bandwidth. | Choose for direct drop-in replacement where gain reduction improves settling or bandwidth. |
Compared with ADA4940-2ARMZ, LTC6363IMS8-2#TRPBF trades 3.05nV/√Hz higher noise for 3.3mA lower quiescent current and eliminates resistor matching risk; versus LTC6363IMS8-1#TRPBF, it doubles gain at the cost of 10MHz bandwidth reduction - optimizing for resolution over speed in SAR-driven systems.

FAQ
What is the maximum operating temperature for the LTC6363IMS8-2#TRPBF?
The LTC6363IMS8-2#TRPBF is rated for operation from –40°C to +85°C (I-grade). Its absolute maximum junction temperature is 150°C, and thermal resistance θJA is 273°C/W in the MS8 package - requiring appropriate PCB copper area for sustained high-temperature operation.
Does the LTC6363IMS8-2#TRPBF require external resistors to set gain?
No. The LTC6363IMS8-2#TRPBF has internal laser-trimmed resistors configured for fixed 2V/V differential gain. Unlike the base LTC6363, it does not require external gain-setting resistors - reducing component count, layout complexity, and matching errors.
Can the LTC6363IMS8-2#TRPBF drive the LTC2378-20 20-bit ADC directly?
Yes. The LTC6363IMS8-2#TRPBF is explicitly characterized driving the LTC2378-20 in the datasheet, achieving 101.8dB SINAD and 118dB SFDR at 2kHz. Its 15MHz bandwidth, 830ns 18-bit settling, and rail-to-rail outputs meet all interface requirements without additional buffering.
What is the VOCM pin function on the LTC6363IMS8-2#TRPBF?
The VOCM pin sets the common-mode voltage of the differential outputs. When left unconnected, it self-biases to ~4.79–5.21V at VS = 10V. It can also be driven externally to precisely control output common-mode level - essential for matching ADC input requirements or rejecting supply noise.
How does shutdown mode affect performance recovery time on the LTC6363IMS8-2#TRPBF?
In shutdown mode, the LTC6363IMS8-2#TRPBF draws ≤130µA and disables the output stage. Turn-on time is specified at 4μs - allowing rapid reactivation between ADC conversion cycles in duty-cycled systems without compromising measurement accuracy.
