Product details
Overview
LTC2310HMSE-16#PBF 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 automotive and industrial systems requiring precision and temperature robustness.
For engineers reviewing the LTC2310HMSE-16#PBF datasheet, LTC2310HMSE-16#PBF pinout, LTC2310HMSE-16#PBF application, or LTC2310HMSE-16#PBF equivalent, this page delivers verified specifications, thermal-grade packaging details (–40°C to +125°C), real-world timing behavior (no cycle latency, 220 ns conversion time), and validated alternative options for signal chain design continuity.
Technical Context
The LTC2310HMSE-16#PBF implements a true differential SAR architecture with no pipeline latency, enabling deterministic real-time sampling. Its internal 4.096 V reference exhibits ≤20 ppm/°C drift over –40°C to +125°C, and its analog front-end accepts 8 VP-P differential inputs while maintaining 85 dB CMRR at 500 kHz.
It features dual-mode digital I/O: CMOS (1.8 V–2.5 V OVDD) or LVDS (2.5 V OVDD, 100 Ω termination), with configurable nap/sleep modes reducing current to 0.5 µW in sleep at 5 V. The device uses a 16-lead MSOP package with exposed pad (Pin 17) tied to GND for thermal and noise performance.

Pinout & Package
Package: 16-lead plastic MSOP (4 mm × 5 mm), exposed pad (Pin 17) soldered to PCB ground plane for thermal management and noise reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11, 17) | Ground reference and thermal path | Multiple dedicated GND pins plus exposed pad ensure low-impedance return paths and stable reference for high-resolution ADC operation. |
| REFIN (Pin 2) | 1.25 V buffered reference I/O | Provides 1.25 V output; grounding disables REFOUT buffer to enable external reference injection into REFOUT pin. |
| REFOUT (Pin 3) | 4.096 V internal reference output | Delivers temperature-compensated 4.096 V ±0.34%; requires 10 µF local decoupling for optimal SNR performance. |
| VDD (Pin 4) | Analog/digital core supply | Accepts 3.13 V–5.25 V; powers SAR core, reference, and logic - bypass with 1 µF ceramic capacitor adjacent to pin. |
| AIN+, AIN– (Pins 6, 7) | Differential analog input terminals | Support 8 VP-P differential swing with 0 V to VDD common mode range - enables direct interface to op-amp drivers without level-shifting. |
| CNV (Pin 9) | Convert initiation input | TTL-compatible; falling edge triggers acquisition/conversion sequence - low-jitter timing critical for aperture jitter-limited SNR. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | Ground = CMOS; tie to OVDD = LVDS; float = low-power LVDS - configures SDO/SCK driver type without changing PCB layout. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V–2.5 V supply for SDO/SCK logic levels - independent of VDD, allowing interfacing with 1.8 V or 2.5 V FPGA/CPLD I/O banks. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first output on SCK falling edge; logic level referenced to OVDD - used only in CMOS mode; SDO– left unconnected. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Falling-edge triggered; supports up to 64 MHz clock rate - enables fast readout within 250 ns readout window at 2 Msps. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Enables deterministic real-time sampling - output data for each CNV pulse is available immediately after conversion, eliminating pipeline delay in closed-loop control. |
| Dual-mode digital interface | Single-pin configuration (CMOS/LVDS pin) selects between CMOS (low power, 1.8 V/2.5 V) or LVDS (noise-immune, 2.5 V, 100 Ω terminated) I/O - preserves layout while adapting to host system requirements. |
| Wide common mode input range | 0 V to VDD allows direct connection to op-amps operating rail-to-rail - reduces need for level-shifting circuitry and improves signal integrity in high-voltage industrial sensing. |
| Integrated 4.096 V reference | 20 ppm/°C max drift over –40°C to +125°C - meets automotive AEC-Q100 Grade 1 thermal stability without external trimming or compensation components. |
| Nap and sleep power modes | Reduces supply current to 2.8 mA (nap) or 0.1 µA (sleep) - extends battery life in portable test equipment and enables ultra-low-power wake-on-event architectures. |

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, 1.8 V/5 V dual supply, no internal reference - requires external 5 V reference and level-shifting for 1.8 V logic. | Higher resolution and speed but lacks integrated reference and automotive temp grade - better suited for lab instrumentation than embedded automotive use. | Select when ENOB >14.5 bits is required and external reference infrastructure exists; not drop-in due to different pinout and supply scheme. |
| ADS8860IRGET | 16-bit, 1 Msps, 1.8 V only I/O, internal 2.5 V reference, 40 ppm/°C drift - lower power (15 mW) but slower and less thermally stable. | Targeted at portable medical devices and battery-powered test gear - insufficient CMRR and temp range for harsh automotive or industrial settings. | Choose for ultra-low-power, space-constrained designs where 1 Msps suffices and extended temperature operation is not needed. |

FAQ
What is the guaranteed operating temperature range for the LTC2310HMSE-16#PBF?
The LTC2310HMSE-16#PBF is rated for continuous operation from –40°C to +125°C, meeting the H-grade specification defined in the Absolute Maximum Ratings table. This range is fully tested and guaranteed, including all electrical parameters such as INL, SNR, and reference drift - making it suitable for under-hood automotive and industrial edge applications where ambient temperatures exceed 105°C.
Does the LTC2310HMSE-16#PBF require an external reference, or does it include one?
The LTC2310HMSE-16#PBF includes an onboard low-drift 4.096 V temperature-compensated reference (REFOUT, Pin 3) with ≤20 ppm/°C max drift over –40°C to +125°C. An external 1.25 V reference may be applied via REFIN (Pin 2) to override the internal reference, but no external reference is required for standard operation - simplifying BOM and layout for most high-speed acquisition systems.
How does the CMOS/LVDS pin (Pin 10) configure the digital interface of the LTC2310HMSE-16#PBF?
The CMOS/LVDS pin (Pin 10) configures the serial interface mode: grounded for CMOS I/O (1.8 V/2.5 V logic levels), tied to OVDD for LVDS mode (differential SDO+/SDO– and SCK+/SCK–), or left floating for low-power LVDS. This single-pin selection avoids firmware changes or hardware modifications when adapting the LTC2310HMSE-16#PBF to different host processor interfaces.
What is the minimum acquisition time and conversion time for the LTC2310HMSE-16#PBF at 2 Msps?
At 2 Msps, the LTC2310HMSE-16#PBF has a guaranteed acquisition time (tACQ) of 280 ns and conversion time (tCONV) of 220 ns. These values are specified over the full –40°C to +125°C range and enable deterministic timing for real-time control loops - with total cycle time (tCYC) of 500 ns, matching the 2 Msps sample rate requirement.
Can the LTC2310HMSE-16#PBF interface directly with a 1.8 V FPGA I/O bank?
Yes - the LTC2310HMSE-16#PBF supports 1.8 V I/O via its OVDD supply (Pin 12), which accepts 1.71 V to 2.5 V. When configured in CMOS mode (CMOS/LVDS pin grounded), SDO+ (Pin 14) and SCK+ (Pin 16) operate at OVDD-referenced logic levels, enabling direct connection to 1.8 V FPGA I/O banks without level shifters - confirmed by VIH/VIL specs of 0.8×OVDD and 0.2×OVDD.
