Product details
Overview
LTC2310CMSE-12#PBF from Analog Devices (formerly Linear Technology) is a 12-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs, 2 Msps throughput, ±1 LSB INL guaranteed, 73 dB SNR typical at 500 kHz, and wide 0 V to VDD common mode input range. It operates from a single 3.3 V or 5 V supply and integrates a low-drift 4.096 V internal reference - ideal for high-speed data acquisition in automotive sensor interfaces and optical networking front-ends.
For engineers reviewing the LTC2310CMSE-12#PBF datasheet, LTC2310CMSE-12#PBF pinout, LTC2310CMSE-12#PBF application, or LTC2310CMSE-12#PBF equivalent, key selection considerations include its no-cycle-latency serial interface, CMOS/LVDS I/O mode select, 16-lead MSOP package with exposed ground pad, and guaranteed operation from 0°C to 70°C.
Technical Context
The LTC2310CMSE-12#PBF implements a 13-bit SAR architecture with differential sampling switch and on-chip CDAC, supporting true bipolar two's complement output coding. Its acquisition phase connects the 10 pF input capacitance directly to AIN+/AIN– through ~15 Ω RON, enabling precise differential voltage measurement without external configuration.
It features dual-reference capability: an internal 4.096 V (±20 ppm/°C) temperature-compensated reference with buffered REFIN (1.25 V) and REFOUT pins, plus support for external reference injection via REFIN = GND. The CMOS/LVDS pin configures serial I/O mode, allowing flexible interfacing with FPGAs or DSPs at up to 64 MHz SCK frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit + sign (13-bit two's complement output), delivering 32,768 discrete levels across full-scale range. |
| Sampling Rate | 2 Msps maximum, with no cycle latency - enables real-time streaming of high-bandwidth signals without pipeline delay. |
| INL Accuracy | ±1 LSB guaranteed over temperature, ensuring monotonicity and eliminating calibration requirements for precision control loops. |
| SNR | 73 dB typical at fIN = 500 kHz, corresponding to ~12.1 effective bits for demanding dynamic signal analysis. |
| Input Range | ±4.096 V differential (8 VP-P) with 0 V to VDD common mode - supports direct connection to op-amp outputs or transformer-coupled sources. |
| Power Dissipation | 35 mW at VDD = 5 V, 2 Msps; reduces to 0.5 µW in sleep mode - suitable for power-constrained embedded systems. |
| Reference | Integrated 4.096 V ±20 ppm/°C reference; also accepts external 1.25 V reference via REFIN pin for system-level voltage scaling. |
| Operating Temp | 0°C to 70°C (C-grade), validated per Absolute Maximum Ratings and Electrical Characteristics tables. |
Pinout & Package
Package: 16-lead (4 mm × 5 mm) plastic MSOP with exposed thermal pad (Pin 17), lead-free finish, tape-and-reel packaging. Requires soldering of exposed pad 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 connections minimize ground bounce and improve noise immunity in high-speed conversion. |
| REFIN (Pin 2) | Reference buffer I/O | Nominally outputs 1.25 V; grounding disables internal REFOUT buffer to enable external reference injection. |
| REFOUT (Pin 3) | Internal reference output | Provides stable 4.096 V ±20 ppm/°C reference; requires 10 µF local decoupling for optimal SNR. |
| VDD (Pin 4) | Analog/digital supply | Single 3.3 V or 5 V input powering core ADC, reference, and timing logic - simplifies power architecture. |
| AIN+, AIN– (Pins 6, 7) | Differential analog inputs | Accept 0 V to VDD common mode with ±4.096 V differential swing - no external level-shifting required. |
| CNV (Pin 9) | Convert trigger | TTL-compatible input initiating conversion on falling edge; low-jitter requirement ensures aperture jitter ≤1 ps RMS. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | GND = CMOS; OVDD = LVDS; floating = low-power LVDS - enables hardware-configurable digital interface. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V to 2.5 V supply setting logic levels for SDO/SCK - allows interoperability with 1.8 V or 2.5 V host systems. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first output synchronized to SCK falling edge; logic level referenced to OVDD - eliminates level translators. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Accepts single-ended clock up to 64 MHz; timing parameters guarantee reliable readout at 2 Msps. |
Key Features
| Feature | Design Value |
|---|---|
| No-cycle-latency operation | Enables deterministic real-time sampling - critical for closed-loop motor control and time-of-flight sensing where pipeline delay is unacceptable. |
| Dual-reference flexibility | Internal 4.096 V reference or external 1.25 V reference via REFIN pin allows system-level gain matching and multi-channel synchronization. |
| Configurable CMOS/LVDS interface | Hardware-selectable I/O mode eliminates need for external level shifters or serializer ICs - reduces BOM count and layout complexity. |
| Guaranteed 12-bit no-missing-codes | Ensures full code coverage across temperature and supply variations - essential for metrology and medical instrumentation compliance. |
| Low-power nap/sleep modes | Reduces current to 2.8 mA (nap) or 0.1 µA (sleep) - extends battery life in portable test equipment and remote monitoring nodes. |
| High CMRR (85 dB @ 500 kHz) | Maintains accuracy in noisy industrial environments by rejecting common-mode interference on sensor cables or PCB traces. |

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-REEL | 16-bit, 1 Msps, SPI-only (no LVDS), 2.5 V reference only, 75 dB SNR, 10-lead MSOP | Better resolution but lower speed; lacks LVDS interface and dual-reference flexibility | Choose when 16-bit precision outweighs 2 Msps throughput and LVDS noise immunity requirements. |

FAQ
What is the guaranteed operating temperature range for the LTC2310CMSE-12#PBF?
The LTC2310CMSE-12#PBF is rated for 0°C to 70°C (Commercial grade), as confirmed by Absolute Maximum Ratings and Electrical Characteristics tables in the official datasheet. This range is explicitly assigned to part numbers ending in "CMSE", distinguishing it from I-grade (–40°C to 85°C) and H-grade (–40°C to 125°C) variants.
Does the LTC2310CMSE-12#PBF require external reference components for basic operation?
No - the LTC2310CMSE-12#PBF includes an onboard 4.096 V temperature-compensated reference with ±20 ppm/°C drift, and only requires a 10 µF ceramic capacitor on REFOUT (Pin 3) for stable operation. External reference use is optional and enabled by grounding REFIN (Pin 2).
Can the LTC2310CMSE-12#PBF interface directly with a 1.8 V FPGA I/O bank?
Yes - the LTC2310CMSE-12#PBF supports 1.8 V to 2.5 V I/O voltages via the OVDD pin (Pin 12). When OVDD = 1.8 V and CMOS/LVDS (Pin 10) is grounded, SDO+ and SCK+ operate at 1.8 V logic levels, enabling direct connection to 1.8 V FPGA I/O without level shifters.
How does the CMOS/LVDS pin (Pin 10) affect the serial interface behavior of the LTC2310CMSE-12#PBF?
The CMOS/LVDS pin (Pin 10) configures the physical layer: grounded selects CMOS mode (single-ended SDO+/SCK+); tied to OVDD enables LVDS mode (differential SDO+/SDO–, SCK+/SCK–); floating activates low-power LVDS. This hardware-selectable feature eliminates firmware configuration overhead and ensures deterministic interface initialization.
What is the minimum acquisition time required before initiating conversion on the LTC2310CMSE-12#PBF?
The LTC2310CMSE-12#PBF specifies a guaranteed acquisition time (tACQ) of 280 ns over temperature, as documented in the ADC Timing Characteristics table. This value determines the minimum CNV pulse spacing needed to ensure full settling of the internal sampling capacitor prior to conversion start.
