Product details
Overview
LTC2310HMSE-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 interface-ideal for high-speed data acquisition in automotive and industrial systems.
For engineers reviewing the LTC2310HMSE-16#TRPBF datasheet, LTC2310HMSE-16#TRPBF pinout, LTC2310HMSE-16#TRPBF application, or LTC2310HMSE-16#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes operation over –40°C to 125°C, 2 Msps throughput with zero cycle latency, differential input voltage range of ±4.096 V, 1.8 V–2.5 V I/O compatibility, and configurable power modes (nap/sleep) for embedded signal chain optimization.
Technical Context
The LTC2310HMSE-16#TRPBF employs a fully differential SAR architecture with integrated sample-and-hold, achieving 16-bit resolution without missing codes across its full temperature range. Its input stage accepts differential signals with common mode ranging from 0 V to VDD, enabling direct interfacing with sensor front-ends and op-amp drivers without level-shifting.
It features dual-mode digital I/O: CMOS (single-ended SDO+/SCK+) or LVDS (differential SDO±/SCK±), selected via the CMOS/LVDS pin. Internal reference buffer provides 4.096 V (±20 ppm/°C max drift) or 2.048 V, while REFIN supports external 1.25 V buffered reference input-enabling flexible precision scaling in mixed-signal systems.
Key Specifications

Pinout & Package
Package: 16-lead (4 mm × 5 mm) MSOP with exposed thermal pad (Pin 17 = GND). RoHS-compliant, lead-free finish. Tape-and-reel packaging (#TRPBF).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11, 17) | Ground reference | All analog/digital grounds and exposed pad must connect to a low-impedance solid ground plane for noise immunity and thermal dissipation. |
| REFIN (Pin 2) | Reference buffer I/O | Nominally outputs 1.25 V; grounding disables REFOUT buffer to allow external reference injection (1.25 V to VDD). |
| REFOUT (Pin 3) | Internal reference output | Provides 4.096 V (or 2.048 V) temperature-compensated reference; requires 10 µF ceramic decoupling close to pin. |
| VDD (Pin 4) | Analog power supply | Accepts 3.13 V–5.25 V; bypass with 1 µF ceramic capacitor to minimize supply noise coupling into ADC core. |
| AIN+, AIN– (Pins 6, 7) | Differential analog inputs | Support 0 V to VDD common mode; full-scale differential swing = ±REFOUT; no configuration required for unipolar/bipolar/pseudo-differential modes. |
| CNV (Pin 9) | Convert trigger input | TTL-compatible; falling edge initiates conversion and readout; timing-critical for jitter-sensitive sampling. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | GND = CMOS; OVDD = LVDS; floating = low-power LVDS - determines SDO/SCK signaling format and current consumption. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V–2.5 V range; sets logic levels for SDO/SCK; must match host interface voltage (e.g., FPGA bank). |
| SDO+ / SDO– (Pins 14, 13) | Serial data output | LVDS mode: differential output requiring 100 Ω termination at receiver; CMOS mode: SDO+ active, SDO– unused. |
| SCK+ / SCK– (Pins 16, 15) | Serial clock input | LVDS mode: differential clock with 100 Ω termination; CMOS mode: SCK+ active, SCK– unused; min period = 15.6 ns (64 MHz). |
Key Features
| Feature | Design Value |
|---|---|
| No missing codes over full temperature range | Guaranteed 16-bit monotonicity enables reliable closed-loop control without code gaps or non-monotonic transitions. |
| Zero cycle latency | Immediate availability of conversion result after CNV edge eliminates pipeline delay-critical for real-time servo and protection algorithms. |
| Configurable I/O interface (CMOS/LVDS) | Single part supports both low-power microcontroller interfaces (CMOS) and high-noise-immunity FPGA links (LVDS), reducing BOM count. |
| Integrated 4.096 V reference with 20 ppm/°C max drift | Eliminates need for external precision reference IC and associated layout complexity in space-constrained designs. |
| Nap and sleep power modes | Reduces current to 2.8 mA (nap) or 0.1 µA (sleep) - extends battery life in portable instrumentation and wake-on-event 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, 1.8 V/5 V dual supply, no internal reference, LVDS-only interface | Higher resolution and speed but requires external reference and level-shifting; larger 32-lead LFCSP package | Select when ENOB > 14.5 bits is mandatory and board space allows larger footprint and additional support components. |
| ADS8860IRGET | 16-bit, 1 Msps, 2.5 V–5 V supply, internal 2.5 V reference, SPI-only CMOS interface, –40°C to +85°C | Lower speed, narrower temp range, no LVDS option, smaller 20-pin QFN package | Select for cost-sensitive industrial controls where 1 Msps suffices and extended temperature operation is not required. |
Compared with AD7960BCPZ-RL7 and ADS8860IRGET, the LTC2310HMSE-16#TRPBF uniquely balances 2 Msps throughput, integrated 4.096 V reference, dual CMOS/LVDS I/O, and full automotive-grade temperature range in a compact MSOP-making it optimal for thermally demanding, noise-sensitive, and space-constrained real-time acquisition systems.

FAQ
What is the maximum sampling rate supported by the LTC2310HMSE-16#TRPBF?
The LTC2310HMSE-16#TRPBF supports a maximum sampling rate of 2 Msps, with guaranteed performance across its full operating temperature range (–40°C to +125°C). This rate is achievable with either CMOS or LVDS interface modes, and the device exhibits zero cycle latency-meaning the conversion result is available immediately after the CNV pulse without pipelining delay. At this rate, the minimum time between conversions is 500 ns.
Does the LTC2310HMSE-16#TRPBF require an external reference voltage?
No, the LTC2310HMSE-16#TRPBF does not require an external reference voltage. It integrates a low-drift, temperature-compensated 4.096 V (or 2.048 V) internal reference buffer on-chip. However, it also provides a 1.25 V buffered REFIN pin that can be used to inject an external reference or disable the internal REFOUT buffer-offering design flexibility for systems needing alternative reference voltages or improved long-term stability.
How does the CMOS/LVDS pin (Pin 10) affect interface configuration for the LTC2310HMSE-16#TRPBF?
The CMOS/LVDS pin (Pin 10) configures the digital interface mode of the LTC2310HMSE-16#TRPBF: grounding selects CMOS (single-ended SDO+/SCK+), tying to OVDD selects standard LVDS (differential SDO±/SCK±), and leaving it floating enables low-power LVDS mode. This pin directly determines driver strength, termination requirements, and power consumption-allowing one hardware design to support multiple host interface standards without redesign.
What power-saving modes are available on the LTC2310HMSE-16#TRPBF, and how much current do they draw?
The LTC2310HMSE-16#TRPBF offers two power-saving modes: Nap mode draws 2.8 mA (typ) at 5 V and Sleep mode draws 0.1 µA (typ) at 5 V. Nap mode retains reference and digital state for fast wake-up (<10 µs), while Sleep mode shuts down most circuitry for ultra-low quiescent current. Both modes are controlled via dedicated command sequences over the SPI interface and are fully functional across the –40°C to +125°C temperature range.
Is the LTC2310HMSE-16#TRPBF pin-compatible with other members of the LTC2310 family?
Yes, the LTC2310HMSE-16#TRPBF is pin-compatible with other temperature-grade variants in the LTC2310-16 family-including the LTC2310CMSE-16#TRPBF (0°C to 70°C) and LTC2310IMSE-16#TRPBF (–40°C to 85°C)-all sharing identical 16-lead MSOP packaging, pinout, and electrical interface. This allows drop-in replacement during design validation or production ramp without PCB layout changes, provided thermal and reliability requirements align with the selected grade.
