Product details
Overview
LTC6362CMS8#TRPBF from Analog Devices (formerly Linear Technology) is a precision, low-power, fully differential op amp optimized as a SAR ADC driver. It delivers 1mA supply current, 200µV max input-referred offset voltage, 3.9nV/√Hz input noise, rail-to-rail I/O, and 550ns settling to 18-bit (4ppm) accuracy - enabling high-fidelity signal conditioning in battery-powered instrumentation and industrial data acquisition systems.
For engineers reviewing the LTC6362CMS8#TRPBF datasheet, LTC6362CMS8#TRPBF pinout, LTC6362CMS8#TRPBF application, or LTC6362CMS8#TRPBF equivalent, key selection criteria include its guaranteed –40°C to 85°C operation (I-grade), MSOP-8 package compatibility, shutdown current of 70µA, differential output balance better than –57dB, and validated performance driving 16-/18-bit SAR ADCs like the LTC2379-18.
Technical Context
The LTC6362CMS8#TRPBF implements a fully differential architecture with independent common-mode feedback via the VOCM pin, enabling precise output common-mode control regardless of input common-mode voltage. Its internal resistor divider sets VOCM to 2.5V when unconnected under 5V supply, and it supports external VOCM overdrive within 0.5V to 4.5V.
It operates from a single 2.8V–5.25V supply, features true rail-to-rail inputs and outputs, and integrates input protection diodes for ±10mA absolute maximum input current. The amplifier achieves 180MHz gain-bandwidth product and 34MHz –3dB bandwidth with 1kΩ feedback, supporting fast-settling, low-distortion signal conversion for high-speed data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.8V to 5.25V - enables direct interface with common ADC reference voltages and low-voltage microcontrollers. |
| Supply Current (Active) | 1.06mA typ at 5V - ensures <1.1mW power consumption, critical for portable and energy-constrained systems. |
| Input Offset Voltage | 200µV max - guarantees ≤0.003% full-scale error in 18-bit systems with ±4V differential output swing. |
| Differential Output Settling | 550ns to 18-bit (4ppm) - meets timing budgets for 1.6Msps SAR ADCs like LTC2379-18 without dead-time penalties. |
| Input Noise Density | 3.9nV/√Hz - contributes <101.2dB SNR in typical 8VP-P configurations, preserving dynamic range in precision measurement. |
| Harmonic Distortion | –116dBc HD2 at 1kHz, 8VP-P - suppresses even-order distortion critical for differential signal integrity and spectral purity. |
| Shutdown Current | 70µA max - reduces system standby power by >93% versus active mode, supporting duty-cycled sensor interfaces. |
Pinout & Package
Package: 8-lead MSOP (MS8), 3mm × 3mm footprint, exposed pad connected to V– for thermal and electrical grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: –IN | Inverting input | Rail-to-rail input stage; accepts signals from V– to V+; protected by back-to-back diodes against >1.4V differential overvoltage. |
| 2: VOCM | Output common-mode reference | Sets VOUTCM = (V+OUT + V–OUT)/2; internal 2.5V divider at 5V supply; 170kΩ input resistance allows direct ADC reference connection. |
| 3: V+ | Positive supply | Accepts 2.8V–5.25V single supply; PSRR >105dB minimizes supply ripple coupling into differential output. |
| 4: +OUT | Positive differential output | Rail-to-rail swing; sources/sinks up to 35mA; requires series R (10–100Ω) for >10pF capacitive loads to prevent peaking. |
| 5: –OUT | Negative differential output | Complementary to +OUT; matched drive strength ensures balanced output impedance and harmonic cancellation. |
| 6: V– | Negative supply / Exposed pad | Typically 0V ground; exposed pad must be soldered to PCB for thermal management (θJC = 45°C/W). |
| 7: SHDN | Shutdown control | Logic-low (≤0.8V) disables amplifier; draws 70µA; floating or tied to V+ enables normal operation. |
| 8: +IN | Noninverting input | Rail-to-rail input stage; symmetric with –IN; input bias current ≤260nA max ensures low error with high-Z sensor sources. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ADC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8138ARMZ | Higher supply current (20mA), wider supply range (±2.5V to ±5.5V), no shutdown mode, 3.5nV/√Hz noise. | Requires dual supply; not suitable for single-supply, low-power battery systems. | Select AD8138ARMZ only when dual supply and higher speed (>350MHz GBW) are required; avoid for <2mA power budgets. |
| THS4561IRGET | Lower noise (1.6nV/√Hz), higher bandwidth (1.8GHz GBW), 2.5mA supply current, no integrated VOCM buffer. | Needs external VOCM generation circuitry; higher power invalidates use in energy-sensitive designs. | Choose THS4561IRGET for RF/IF applications demanding sub-2nV/√Hz noise and GHz bandwidth; not recommended for SAR ADC driving below 10Msps. |
Compared with AD8138ARMZ and THS4561IRGET, the LTC6362CMS8#TRPBF uniquely balances ultra-low power (1mA), integrated VOCM control, guaranteed 18-bit settling, and single-supply operation - making it the optimal choice for precision, portable, and industrial SAR ADC interfaces where power, simplicity, and DC accuracy are prioritized over raw speed or dual-supply flexibility.

FAQ
What is the operating temperature range for the LTC6362CMS8#TRPBF?
The LTC6362CMS8#TRPBF is an I-grade part rated for –40°C to +85°C operation, with full electrical specifications guaranteed across this range. It uses the MSOP-8 package and is distinct from the C-grade (0°C to 70°C) and H-grade (–40°C to 125°C) variants. This makes the LTC6362CMS8#TRPBF suitable for industrial environments where ambient temperatures exceed commercial limits but do not reach extended automotive extremes.
Does the LTC6362CMS8#TRPBF require external resistors for gain configuration?
Yes, the LTC6362CMS8#TRPBF is a fully differential amplifier requiring external feedback (RF) and gain-setting (RI) resistors to define closed-loop gain and common-mode behavior. Typical configurations use matched 1kΩ resistors for unity gain. The device does not include internal gain-setting components; all gain and feedback networks must be implemented externally per the application circuit in the datasheet.
Can the VOCM pin of the LTC6362CMS8#TRPBF be left unconnected?
Yes - the VOCM pin of the LTC6362CMS8#TRPBF has an internal resistor divider that defaults to 2.475V–2.525V with a 5V supply. Leaving it unconnected is valid for applications where that common-mode level matches the ADC's requirement. However, for precise control or non-2.5V ADCs (e.g., 0.9V or 1.8V references), VOCM must be driven externally with a low-impedance source capable of driving its 110–230kΩ input resistance.
How does the LTC6362CMS8#TRPBF handle input overvoltage conditions?
The LTC6362CMS8#TRPBF includes robust input protection: back-to-back diodes between +IN and –IN limit differential input voltage to ~1.4V, and steering diodes clamp each input to V+ and V– rails. Input current must be limited to <±10mA under overvoltage to prevent damage. This protection enables safe interfacing with sensors or switches that may transiently exceed supply rails in harsh industrial settings.
Is the LTC6362CMS8#TRPBF pin-compatible with other members of the LTC6362 family?
Yes - all LTC6362 variants (e.g., LTC6362IMS8#TRPBF, LTC6362HMS8#TRPBF, LTC6362CDD#TRPBF) share identical pinouts across MSOP-8 and DFN-8 packages. The LTC6362CMS8#TRPBF uses the same 8-pin MSOP layout as the I- and H-grade MSOP versions, differing only in temperature grade and ordering suffix. PCB layouts designed for any MSOP variant can accommodate the LTC6362CMS8#TRPBF without modification.
