Product details
Overview
LTC2311CMSE-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 5 Msps successive approximation register (SAR) analog-to-digital converter with differential inputs, ±3 LSB typical INL, 81 dB SNR at 2.2 MHz input, and integrated 4.096 V temperature-compensated reference - designed for high-speed data acquisition in industrial instrumentation and optical networking systems.
For engineers reviewing the LTC2311CMSE-16#TRPBF datasheet, LTC2311CMSE-16#TRPBF pinout, LTC2311CMSE-16#TRPBF application, or LTC2311CMSE-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation, wide 0 V to VDD common-mode input range, CMOS/LVDS configurable serial interface, and –40°C to 70°C operating temperature range per the C-grade specification.
Technical Context
The LTC2311CMSE-16#TRPBF implements a single-supply SAR architecture with one-cycle latency and internal sampling capacitor switching. Its differential front-end supports arbitrary common-mode voltages from GND to VDD while rejecting noise via >85 dB CMRR at 2.2 MHz.
It integrates dual reference paths: a factory-trimmed 4.096 V (±20 ppm/°C max) buffered output and a 1.25 V buffered REFIN pin that disables REFOUT when grounded - enabling flexible external reference use. The CMOS/LVDS mode select pin (Pin 10) configures I/O signaling without hardware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 discrete output levels with guaranteed no missing codes. |
| Sampling Rate | 5 Msps - enables real-time digitization of signals up to ~2.2 MHz Nyquist bandwidth. |
| INL (typ) | ±3 LSB - ensures accurate amplitude representation across full-scale range for precision measurement. |
| SNR (typ) | 81.6 dB at fIN = 2.2 MHz - supports >13.2 ENOB for high-fidelity signal capture. |
| Reference | Internal 4.096 V ±20 ppm/°C - eliminates need for external reference in most applications; REFIN accepts 1.25 V external source. |
| Supply | Single 3.3 V or 5 V - simplifies power design; OVDD supports 1.71 V to 2.5 V I/O logic compatibility. |
| Power (5V/5Msps) | 50 mW typical - balances speed and efficiency for thermally constrained embedded systems. |
Pinout & Package
Package: 16-lead (4 mm × 5 mm) plastic MSOP with exposed thermal pad (Pin 17), RoHS-compliant, tape-and-reel packaging (#TRPBF).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11) | Analog/digital ground reference | Must connect directly to solid ground plane; multiple pins reduce impedance and improve noise immunity. |
| REFIN (Pin 2) | 1.25 V reference buffer I/O | Outputs 1.25 V by default; grounding disables REFOUT buffer to allow external reference injection. |
| REFOUT (Pin 3) | 4.096 V reference output | Provides low-drift internal reference; requires 10 µF local decoupling for stability. |
| VDD (Pin 4) | Analog power supply | Accepts 3.3 V or 5 V; bypassed with 1 µF ceramic capacitor near pin. |
| AIN+, AIN– (Pins 6, 7) | Differential analog input | Supports 8 VP-P differential swing with 0 V to VDD common-mode range - no configuration needed. |
| CNV (Pin 9) | Convert timing control | TTL-compatible input; falling edge initiates conversion and triggers serial readout. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | GND = CMOS; OVDD = LVDS; floating = low-power LVDS - sets signaling standard dynamically. |
| OVDD (Pin 12) | Digital I/O power supply | 1.71 V to 2.5 V range - matches FPGA/CPLD I/O voltage for level compatibility. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first output on SCK falling edge; logic level referenced to OVDD. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Accepts single-ended clock up to 105 MHz; falling edge clocks data out. |
Key Features
| Feature | Design Value |
|---|---|
| Differential input with wide common-mode range | 0 V to VDD common-mode support enables direct interfacing with op-amp outputs and sensor bridges without level-shifting. |
| Configurable CMOS/LVDS serial interface | Single-pin mode selection allows interoperability with both FPGA CMOS banks and high-speed LVDS receivers without redesign. |
| Onboard 4.096 V reference with <20 ppm/°C drift | Eliminates external reference component count and layout area while maintaining accuracy over industrial temperature range. |
| One-cycle latency and 5 Msps throughput | Enables deterministic real-time control loops and streaming acquisition with minimal pipeline delay. |
| Nap/sleep modes reducing current to ≤10 µA | Extends battery life in portable test equipment and enables rapid wake-up (<10 ms REFOUT stabilization) for burst-mode sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7960BCPZ-RL7 | 18-bit, 5 Msps, SPI-only (no LVDS), 3.3 V only, 91.5 dB SNR, higher power (65 mW) | Higher resolution but less flexible I/O; requires external reference and stricter layout for 18-bit performance | Select when 18-bit resolution and maximum SNR outweigh I/O flexibility and power constraints. |
| ADS8860IRGET | 16-bit, 1 Msps, SPI-only, 3.3 V only, 86 dB SNR, lower power (12 mW), no internal reference | Lower speed and no LVDS; requires external reference and driver; better suited for portable/battery-powered systems | Select when lower throughput and ultra-low power are prioritized over speed and interface versatility. |
Compared with AD7960BCPZ-RL7 and ADS8860IRGET, the LTC2311CMSE-16#TRPBF uniquely combines 5 Msps speed, integrated 4.096 V reference, and dual CMOS/LVDS I/O in a compact MSOP package - making it optimal for space-constrained, mixed-signal systems needing rapid deployment without reference or level-shifter design overhead.

FAQ
What is the operating temperature range for the LTC2311CMSE-16#TRPBF?
The LTC2311CMSE-16#TRPBF is specified for 0°C to 70°C operation (C-grade). This is confirmed in the "ORDER INFORMATION" table where "LTC2311CMSE-16#TRPBF" is explicitly listed with "0°C to 70°C" under "TEMPERATURE RANGE". It differs from I-grade (–40°C to 85°C) and H-grade (–40°C to 125°C) variants.
Does the LTC2311CMSE-16#TRPBF require an external reference?
No, the LTC2311CMSE-16#TRPBF includes an onboard 4.096 V temperature-compensated reference with ≤20 ppm/°C drift. The REFIN pin provides a 1.25 V buffered output and can accept an external reference when grounded to disable the internal REFOUT buffer - making external reference optional, not required.
How does the CMOS/LVDS pin (Pin 10) configure the serial interface on the LTC2311CMSE-16#TRPBF?
Pin 10 (CMOS/LVDS) selects the interface mode: grounding enables CMOS I/O (single-ended SDO+/SCK+), tying to OVDD enables LVDS (differential SDO+/SDO–, SCK+/SCK–), and leaving it floating enables low-power LVDS. This is documented in the "PIN FUNCTIONS" section and functional block diagrams for both modes.
What is the guaranteed integral nonlinearity (INL) specification for the LTC2311CMSE-16#TRPBF?
The LTC2311CMSE-16#TRPBF guarantees ±8 LSB INL over temperature, with ±3 LSB typical performance. This is stated in the "ELECTRICAL CHARACTERISTICS" table under "INL Integral Linearity Error", where the "MIN" and "MAX" columns show –8 and +8 LSB respectively for conditions marked with "l" (full temperature range).
Can the LTC2311CMSE-16#TRPBF operate from a 3.3 V supply?
Yes, the LTC2311CMSE-16#TRPBF operates from either a 3.3 V or 5 V single supply, as confirmed in the "DESCRIPTION" and "POWER REQUIREMENTS" sections. At 3.3 V, typical power dissipation is 30 mW (CMOS mode, 5 Msps), and OVDD must be set between 1.71 V and 2.5 V for compatible I/O logic levels.
