Product details
Overview
LTC2310IMSE-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 2 Msps successive approximation register (SAR) analog-to-digital converter with differential inputs, ±3 LSB typical INL, 82 dB SNR 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, integrates a low-drift 4.096 V internal reference, and supports CMOS or LVDS SPI-compatible serial I/O - ideal for high-speed data acquisition in industrial instrumentation and optical networking.
For engineers reviewing the LTC2310IMSE-16#TRPBF datasheet, LTC2310IMSE-16#TRPBF pinout, LTC2310IMSE-16#TRPBF application, or LTC2310IMSE-16#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes 16-bit resolution, –40°C to 85°C operating temperature range (I-grade), 220 ns conversion time, 8 VP-P differential input span, and dual-mode (CMOS/LVDS) digital interface compatibility with 1.8 V–2.5 V I/O voltages.
Technical Context
The LTC2310IMSE-16#TRPBF employs a precision SAR architecture with integrated sample-and-hold, delivering no cycle latency and deterministic timing across full 2 Msps throughput. Its differential front-end achieves 85 dB common-mode rejection at 500 kHz while accepting arbitrary input relationships between AIN+ and AIN– within 0 V to VDD.
It features dual-reference capability: a factory-trimmed 4.096 V internal reference (20 ppm/°C max drift) and a buffered 1.25 V external reference input (REFIN), enabling flexible system-level voltage scaling. The configurable CMOS/LVDS I/O interface (selected via Pin 10) supports interoperability with FPGAs, DSPs, and ASICs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonic transfer function and no missing codes over full temperature range. |
| Sampling Rate | 2 Msps - enables real-time capture of signals up to 1 MHz Nyquist bandwidth with zero pipeline latency. |
| INL (Typ) | ±3 LSB - ensures accurate amplitude fidelity in precision measurement applications such as sensor signal conditioning. |
| SNR (Typ) | 82 dB at fIN = 500 kHz - supports >13.3 ENOB for high-fidelity digitization of medium-frequency analog waveforms. |
| Differential Input Range | ±4.096 V (8 VP-P) - allows direct interfacing with ±4 V sensors or op-amp outputs without attenuation or gain stages. |

Pinout & Package
Package: 16-lead plastic MSOP (4 mm × 5 mm), exposed pad (Pin 17) soldered to ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11) | Ground reference | Multiple dedicated ground pins minimize ground bounce and improve PSRR during high-speed conversion. |
| REFIN (Pin 2) | 1.25 V reference buffer I/O | Provides buffered 1.25 V output; grounding disables REFOUT buffer to allow external reference injection into REFOUT. |
| REFOUT (Pin 3) | 4.096 V reference output | Low-drift internal reference output; requires 10 µF ceramic decoupling for stability and noise suppression. |
| VDD (Pin 4) | Analog/digital power supply | Single 3.3 V or 5 V supply powers entire ADC core and reference; bypassed with 1 µF ceramic capacitor. |
| AIN+, AIN– (Pins 6, 7) | Differential analog inputs | Accept 0 V to VDD common mode; support pseudo-differential and fully differential configurations without reconfiguration. |
| CNV (Pin 9) | Convert trigger input | TTL-compatible control input initiates conversion on falling edge; timing-critical for synchronization with host controller. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | GND = CMOS mode; OVDD = LVDS mode; floating = low-power LVDS - configures physical layer without firmware change. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V–2.5 V supply sets logic levels for SDO/SCK; decoupled with 1 µF ceramic capacitor near pin. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first SPI-compatible output; active only in CMOS mode; logic level referenced to OVDD. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Falling-edge clocked interface; supports up to 64 MHz SCK frequency; logic level referenced to OVDD. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Enables deterministic real-time control loops by eliminating pipeline delay between CNV assertion and first valid data. |
| Configurable CMOS/LVDS interface | Reduces board-level complexity: same device supports FPGA LVDS receivers or microcontroller CMOS SPI peripherals without redesign. |
| Wide input common mode range (0 V to VDD) | Eliminates need for input biasing networks when digitizing signals referenced to non-ground potentials (e.g., current-sense amplifiers). |
| Integrated 4.096 V reference with 20 ppm/°C drift | Meets industrial temperature requirements without external trimming or calibration, reducing BOM count and test overhead. |
| Nap and sleep modes | Reduces quiescent current to 4 µA (sleep, VDD = 5 V), enabling ultra-low-power wake-on-event architectures in battery-operated DAQ systems. |

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, 2.5 V supply only, no integrated reference, SPI-only (no LVDS) | Higher resolution but requires external reference and level-shifting for 3.3 V/5 V systems; lacks LVDS for long-reach FPGA links | Select when ENOB >14.5 is required and system can accommodate external reference design complexity. |
| MAX11198ETK+ | 16-bit, 2 Msps, 3.3 V only, internal 2.048 V reference, CMOS I/O only, smaller 12-pin TDFN | Lower power (15 mW), but limited to 3.3 V operation and lacks LVDS interface and wide common mode flexibility | Select for compact, low-power, cost-sensitive 3.3 V systems where LVDS and bipolar input range are unnecessary. |
Compared with AD7960BCPZ-RL7 and MAX11198ETK+, the LTC2310IMSE-16#TRPBF uniquely balances 2 Msps speed, integrated 4.096 V reference, dual-voltage supply (3.3 V/5 V), and LVDS/CMOS configurability - making it optimal for mixed-signal systems requiring robustness, flexibility, and minimal external components.

FAQ
What is the operating temperature range for the LTC2310IMSE-16#TRPBF?
The LTC2310IMSE-16#TRPBF is rated for operation from –40°C to +85°C (I-grade). This specification is guaranteed across all electrical parameters in the datasheet, including INL, SNR, and reference accuracy, making it suitable for industrial and automotive under-hood environments where thermal stability is critical. The LTC2310IMSE-16#TRPBF uses the same die as the H-grade (–40°C to +125°C) variant but is binned and tested to the I-grade limits.
Does the LTC2310IMSE-16#TRPBF require an external reference?
No, the LTC2310IMSE-16#TRPBF includes a factory-trimmed, low-drift 4.096 V internal reference with 20 ppm/°C maximum temperature coefficient. An external reference is optional and applied via the REFIN pin to disable the internal buffer and drive REFOUT directly - useful when system-level calibration or tighter reference tolerance is needed. The LTC2310IMSE-16#TRPBF functions fully with only its internal reference enabled.
How does the CMOS/LVDS pin (Pin 10) configure the digital interface of the LTC2310IMSE-16#TRPBF?
Pin 10 (CMOS/LVDS) selects the serial interface mode: grounded for CMOS mode (single-ended SDO+/SCK+), tied to OVDD for standard LVDS mode (differential SDO+/SDO–, SCK+/SCK–), or left floating for low-power LVDS mode. This hardware-selectable configuration allows the LTC2310IMSE-16#TRPBF to interface directly with either CMOS microcontrollers or LVDS-capable FPGAs without PCB redesign or firmware changes.
What is the significance of "no cycle latency" in the LTC2310IMSE-16#TRPBF?
"No cycle latency" means the LTC2310IMSE-16#TRPBF outputs the conversion result of the *current* CNV-triggered sample immediately after tCONV (220 ns), with no pipelined delay. Unlike sigma-delta or pipeline ADCs, there is no offset between trigger and first valid data - enabling precise time-of-flight measurements, real-time control loop closure, and deterministic sampling in systems like motor control or ultrasound beamforming where timing predictability is essential. The LTC2310IMSE-16#TRPBF delivers this behavior across its full 2 Msps rate.
Can the LTC2310IMSE-16#TRPBF digitize single-ended signals?
Yes, the LTC2310IMSE-16#TRPBF supports pseudo-differential single-ended operation without configuration: connect the signal to AIN+ and a clean reference (e.g., ground or mid-rail) to AIN–. Its wide 0 V to VDD common mode range and 85 dB CMRR at 500 kHz reject noise common to both inputs. This capability is inherent to the LTC2310IMSE-16#TRPBF's architecture - no register writes or mode settings are required, simplifying firmware and layout.
