Product details
Overview
LTC2311HMSE-14#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs, 5 Msps throughput, ±0.75 LSB typical INL, 80 dB SNR at 2.2 MHz, and guaranteed operation from –40°C to 125°C. It integrates a low-drift 4.096 V internal reference and supports CMOS or LVDS serial interface - ideal for high-speed data acquisition in harsh-environment industrial and automotive systems.
For engineers reviewing the LTC2311HMSE-14#TRPBF datasheet, LTC2311HMSE-14#TRPBF pinout, LTC2311HMSE-14#TRPBF application, or LTC2311HMSE-14#TRPBF equivalent, key selection criteria include its wide input common mode range (0 V to VDD), 8 VP-P differential input span, one-cycle latency, 50 mW power dissipation at 5 V, and MSOP-16 package with exposed ground pad for thermal management.
Technical Context
The LTC2311HMSE-14#TRPBF employs a 15-bit SAR architecture delivering 14-bit resolution with sign bit, achieving no missing codes across temperature. Its differential sampling switch network and on-chip 4.096 V reference buffer enable precise digitization of signals with up to 85 dB common-mode rejection at 2.2 MHz.
Timing is controlled by a single CNV pulse initiating conversion; output data appears on SDO (CMOS) or SDO+/SDO– (LVDS) with falling-edge clock capture. The device supports three I/O modes - CMOS, LVDS, and low-power LVDS - selected via the CMOS/LVDS pin, and includes nap/sleep modes reducing current to ≤10 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit + sign (15-bit two's complement output); enables bipolar signal digitization without external level-shifting. |
| Sampling Rate | 5 Msps maximum; supports real-time capture of signals up to ~2.2 MHz Nyquist bandwidth. |
| INL | ±0.75 LSB typical, ±2 LSB guaranteed; ensures monotonicity and accurate full-scale linearity in precision measurement. |
| SNR | 80.6 dB typical at fIN = 2.2 MHz; delivers >13.3 effective bits for high-fidelity signal reconstruction. |
| Input Range | ±4.096 V differential (8 VP-P) with 0 V to VDD common mode; accommodates wide-swing sensor outputs directly. |
| Reference | Internal 4.096 V ±0.3% buffered reference, 20 ppm/°C max drift; eliminates need for external precision reference in most applications. |
| Power @ 5V | 50 mW typical at 5 Msps; enables high-speed acquisition in thermally constrained embedded systems. |
Pinout & Package
Package: 16-lead (4 mm × 5 mm) plastic MSOP with exposed pad (Pin 17), rated for –40°C to 125°C operation. Exposed pad must be soldered to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11) | Ground reference | Multiple dedicated ground pins minimize ground bounce and improve noise immunity in high-speed conversion. |
| REFIN (Pin 2) | 1.25 V reference buffer I/O | Can source 1.25 V or accept external reference; grounding disables REFOUT buffer for external reference injection. |
| REFOUT (Pin 3) | 4.096 V reference output | Low-drift buffered output; requires 10 µF ceramic decoupling close to pin for stability and noise reduction. |
| VDD (Pin 4) | Analog supply | Accepts 3.3 V or 5 V; bypass with 1 µF ceramic capacitor to suppress supply noise coupling into ADC core. |
| AIN+, AIN– (Pins 6, 7) | Differential analog inputs | Support 0 V to VDD common mode; 10 pF input capacitance and 15 Ω switch RON define acquisition dynamics. |
| CNV (Pin 9) | Convert trigger input | TTL-compatible; rising edge initiates sampling, falling edge starts conversion and readout - enables precise timing control. |
| CMOS/LVDS (Pin 10) | I/O mode select | Ground = CMOS; OVDD = LVDS; floating = low-power LVDS - configures interface without external logic. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V to 2.5 V range; sets logic levels for SDO/SCK and isolates digital noise from analog section. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first output synchronized to SCK falling edge; high-impedance when not active. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Single-ended clock input; supports up to 105 MHz for high-throughput SPI communication. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input common mode range | 0 V to VDD allows direct interfacing with op-amp drivers, isolated sensors, or unbuffered transducer outputs without level-shifting circuitry. |
| One-cycle latency | Enables deterministic real-time control loops with minimal processing delay between sample and result availability. |
| Configurable CMOS/LVDS interface | Reduces EMI and improves noise immunity in noisy environments via differential LVDS signaling, or lowers power with CMOS mode. |
| Nap and sleep modes | Reduces quiescent current to ≤10 µA, enabling ultra-low-power wake-on-event architectures in battery-backed or energy-harvesting systems. |
| Guaranteed –40°C to 125°C operation | Validated performance across full automotive and industrial temperature range - no derating required for high-reliability deployments. |

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 |
|---|---|---|---|
| AD7980BRMZ | 16-bit, 1 Msps, 3.3 V only, no integrated reference, SPI-only CMOS interface | Lacks LVDS option and internal reference; requires external 2.5 V ref and level-shifting for wide common mode | Select when higher resolution (16-bit) at lower speed suffices and system already provides precision reference. |
| ADS8860IDRCT | 16-bit, 1 Msps, 2.5–5 V supply, internal 2.5 V ref, no LVDS, smaller 10-pin WSON | Lower speed, no LVDS support, narrower input common mode (0.3 V to VREF), not rated beyond 85°C | Choose for space-constrained, cost-sensitive designs where 125°C rating and differential noise immunity are not required. |
Compared with AD7980BRMZ and ADS8860IDRCT, the LTC2311HMSE-14#TRPBF uniquely combines 5 Msps speed, integrated 4.096 V reference, LVDS/CMOS flexibility, and extended temperature grade - making it optimal for ruggedized, high-throughput industrial and automotive data acquisition where board space, thermal margin, and interface robustness are critical.

FAQ
What is the guaranteed operating temperature range for the LTC2311HMSE-14#TRPBF?
The LTC2311HMSE-14#TRPBF is specified for continuous operation from –40°C to +125°C, with all key parameters - including INL, SNR, and reference accuracy - guaranteed across this full industrial-plus-automotive range. This H-grade qualification is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections of the official datasheet.
Does the LTC2311HMSE-14#TRPBF require an external reference?
No, the LTC2311HMSE-14#TRPBF includes an onboard low-drift 4.096 V temperature-compensated reference buffer (20 ppm/°C max). An external 1.25 V reference can be applied via REFIN, and grounding REFIN disables the internal REFOUT buffer to allow direct external reference injection - but external reference is optional, not required.
How does the CMOS/LVDS pin (Pin 10) configure the serial interface on the LTC2311HMSE-14#TRPBF?
On the LTC2311HMSE-14#TRPBF, Pin 10 (CMOS/LVDS) selects interface mode: grounded for CMOS, tied to OVDD for standard LVDS, or left floating for low-power LVDS. This hardware-selectable configuration avoids firmware overhead and ensures deterministic interface behavior at power-up without requiring initialization code.
What is the minimum acquisition time required before conversion on the LTC2311HMSE-14#TRPBF?
The LTC2311HMSE-14#TRPBF specifies a minimum acquisition time (tACQ) of 28.5 ns over the full temperature range. This short acquisition window - combined with 171.5 ns conversion time - enables the full 5 Msps throughput while maintaining ±0.75 LSB INL performance, as verified in the ADC Timing Characteristics table.
Can the LTC2311HMSE-14#TRPBF digitize single-ended signals without external circuitry?
Yes, the LTC2311HMSE-14#TRPBF supports pseudo-differential unipolar and bipolar configurations natively. For single-ended signals, connect the reference (e.g., ground or mid-supply) to AIN– and the signal to AIN+, leveraging the device's 0 V to VDD common mode range - no external resistors, amplifiers, or level shifters are needed to achieve full 14-bit resolution.
