Product details
Overview
LTC2310HMSE-12#TRPBF 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 over –40°C to 125°C, and integrated 4.096 V temperature-compensated reference. It operates from a single 3.3 V or 5 V supply and delivers 73 dB SNR at 500 kHz input, making it suitable for high-speed industrial data acquisition and motor control systems requiring wide dynamic range and high common-mode rejection.
For engineers reviewing the LTC2310HMSE-12#TRPBF datasheet, LTC2310HMSE-12#TRPBF pinout, LTC2310HMSE-12#TRPBF application, or LTC2310HMSE-12#TRPBF equivalent, key selection considerations include its no-cycle-latency serial interface, CMOS/LVDS I/O mode selectability, 8 VP-P differential input range, internal reference drift ≤20 ppm/°C, and MSOP-16 package with exposed thermal pad.
Technical Context
The LTC2310HMSE-12#TRPBF implements a 13-bit SAR architecture with differential sampling switch and on-chip CDAC, supporting true bipolar two's complement output coding. Its timing logic initiates conversion on CNV falling edge, completes conversion in 220 ns, and outputs data MSB-first on SCK falling edges - with zero cycle latency between conversions.
It integrates dual reference paths: a low-drift 4.096 V internal reference (REFOUT) and a buffered 1.25 V external reference input (REFIN), enabling flexible reference configuration. The CMOS/LVDS pin selects between single-ended CMOS I/O (1.8 V–2.5 V OVDD) and differential LVDS I/O (100 Ω termination), with low-power LVDS mode available via floating pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit + sign (13-bit two's complement output); supports full-scale digitization of ±4.096 V differential input. |
| Sampling Rate | 2 Msps maximum; enables real-time capture of signals up to 1 MHz Nyquist bandwidth without undersampling. |
| INL Error | ±1 LSB guaranteed over full temperature range (–40°C to 125°C); ensures monotonicity and accurate end-point linearity. |
| SNR | 73 dB typical at fIN = 500 kHz; corresponds to ~12.1 effective bits under standard test conditions. |
| Power Dissipation | 35 mW at VDD = 5 V, 2 Msps; reduces to 0.5 µW in sleep mode for ultra-low-power standby. |
| Input Range | ±REFOUT differential (±4.096 V typical); common-mode range spans 0 V to VDD, enabling direct interfacing with op-amp drivers. |
| Reference | Internal 4.096 V ±0.34% (20 ppm/°C max drift); externally configurable via 1.25 V REFIN pin for precision calibration. |
Pinout & Package
Package: 16-lead (4 mm × 5 mm) plastic MSOP with exposed thermal pad (Pin 17), rated for –40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 8, 11, 17) | Ground reference and thermal path | Multiple ground pins and exposed pad must be soldered to solid PCB ground plane for signal integrity and thermal management. |
| REFIN (Pin 2) | 1.25 V reference buffer I/O | Outputs 1.25 V nominal; grounding disables REFOUT buffer to allow external reference injection into REFOUT. |
| REFOUT (Pin 3) | 4.096 V reference output | Low-drift buffered reference; requires 10 µF ceramic decoupling; voltage can be overdriven when REFIN = GND. |
| VDD (Pin 4) | Analog/digital core supply | Accepts 3.13 V–5.25 V; bypass with 1 µF ceramic capacitor; powers SAR core, reference, and timing logic. |
| AIN+, AIN– (Pins 6, 7) | Differential analog input | Supports 8 VP-P swing with 0 V to VDD common-mode range; modeled as 15 Ω RON + 10 pF CIN. |
| CNV (Pin 9) | Convert initiation trigger | TTL-compatible input; falling edge starts acquisition/conversion; unaffected by CMOS/LVDS mode setting. |
| CMOS/LVDS (Pin 10) | I/O interface mode select | Ground = CMOS; connect to OVDD = LVDS; float = low-power LVDS; determines SDO/SCK signaling format. |
| OVDD (Pin 12) | Digital I/O supply | 1.71 V–2.5 V supply for SDO/SCK logic levels; decouple with 1 µF ceramic; sets voltage thresholds for digital interface. |
| SDO+ (Pin 14) | Serial data output (CMOS) | MSB-first output synchronized to SCK falling edge; logic level referenced to OVDD; SDO– unused in CMOS mode. |
| SCK+ (Pin 16) | Serial clock input (CMOS) | Falling-edge triggered; supports up to 64 MHz clock rate; SCK– unused in CMOS mode. |
| SDO+, SDO– (Pins 14, 13) | Differential serial data output (LVDS) | LVDS-mode output pair; requires 100 Ω differential termination at receiver; supports high-noise-immunity data transfer. |
| SCK+, SCK– (Pins 16, 15) | Differential serial clock input (LVDS) | LVDS-mode clock pair; requires 100 Ω differential termination at receiver; enables jitter-tolerant synchronous readout. |
Key Features
| Feature | Design Value |
|---|---|
| No-cycle-latency operation | Enables continuous 2 Msps sampling without dead time between conversions - critical for real-time closed-loop control. |
| Configurable CMOS/LVDS interface | Single pin (Pin 10) selects between low-voltage CMOS (1.8 V/2.5 V) and noise-immune LVDS, simplifying FPGA/ASIC integration. |
| Wide input common-mode range (0 V to VDD) | Eliminates need for level-shifting circuitry when interfacing with op-amps powered from same rail as VDD. |
| Onboard 4.096 V reference with 20 ppm/°C max drift | Reduces BOM count and layout complexity while maintaining <±1 LSB INL over full industrial temperature range. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7980BRMZ-REEL7 | 16-bit, 1 Msps, SPI-only CMOS interface, no integrated reference, requires external 4.096 V ref. | Higher resolution but half the speed; lacks LVDS option and internal reference - increases BOM and layout complexity. | Select when 16-bit resolution outweighs 2 Msps requirement and system already provides precision reference. |
| ADS8860IDRCT | 16-bit, 1 Msps, pseudo-differential input only, 1.8 V supply, no internal reference, no LVDS support. | Lower power (1.5 mW) but limited to unipolar/pseudo-diff inputs; unsuitable for true differential or high-CMRR applications. | Select for battery-powered portable instruments needing 16-bit resolution and minimal power, not for industrial motor control. |

FAQ
What is the operating temperature range of the LTC2310HMSE-12#TRPBF?
The LTC2310HMSE-12#TRPBF is rated for operation from –40°C to +125°C, meeting industrial and automotive under-hood requirements. This H-grade qualification is confirmed in the Absolute Maximum Ratings table and applies to all electrical specifications marked with the "l" symbol in the datasheet, including ±1 LSB INL and 73 dB SNR performance.
Does the LTC2310HMSE-12#TRPBF require an external reference?
No - the LTC2310HMSE-12#TRPBF includes an onboard 4.096 V temperature-compensated reference (REFOUT) with ≤20 ppm/°C drift. An external 1.25 V reference may be applied via REFIN to override the internal reference, but it is not required for basic operation. The device functions fully with only VDD, OVDD, and decoupling capacitors.
How does the CMOS/LVDS pin (Pin 10) affect interface configuration?
The CMOS/LVDS pin (Pin 10) configures the serial interface: grounded for CMOS mode (single-ended SDO+/SCK+), tied to OVDD for standard LVDS mode (differential SDO±/SCK±), or left floating for low-power LVDS mode. This pin directly controls driver strength and termination behavior - no register writes or firmware setup is needed.
Can the LTC2310HMSE-12#TRPBF interface directly with a 1.8 V FPGA I/O bank?
Yes - when OVDD is supplied at 1.8 V and the CMOS/LVDS pin is grounded, the LTC2310HMSE-12#TRPBF's SDO and SCK pins operate at 1.8 V logic levels, matching standard FPGA I/O banks. Input thresholds scale with OVDD (VIH = 0.8 × OVDD, VIL = 0.2 × OVDD), ensuring reliable communication without level shifters.
What is the significance of "no cycle latency" in the LTC2310HMSE-12#TRPBF?
"No cycle latency" means the LTC2310HMSE-12#TRPBF outputs the result of each conversion immediately after tREADOUT (250 ns), with no pipeline delay or dead time before the next CNV pulse can initiate a new conversion. This enables deterministic, gapless sampling at full 2 Msps - essential for real-time control loops and FFT-based spectral analysis.
