Product details
Overview
LTC2313ITS8-14#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit, 2.5 Msps successive approximation register (SAR) analog-to-digital converter in an 8-lead TSOT-23 package. It operates from a single 3V or 5V analog supply, integrates a low-drift (20 ppm/°C max) internal reference (2.048 V or 4.096 V), and delivers 77 dB SINAD and –85 dB THD at full speed-enabling high-fidelity data acquisition in space-constrained, low-power systems such as handheld medical sensors and battery-powered test equipment.
For engineers reviewing the LTC2313ITS8-14#TRPBF datasheet, LTC2313ITS8-14#TRPBF pinout, LTC2313ITS8-14#TRPBF application, or LTC2313ITS8-14#TRPBF equivalent, key selection criteria include guaranteed no missing codes, nap/sleep mode power management, SPI-compatible 3-wire serial interface with 1.8–5 V OVDD compatibility, and operation across –40°C to +85°C industrial temperature range.
Technical Context
The LTC2313ITS8-14#TRPBF implements a fully integrated SAR architecture with on-chip sample-and-hold, bandgap reference, LDO, and reference buffer. Its conversion timing is governed by an internal oscillator, eliminating external clock dependencies for the core ADC function.
It uses a 3-wire serial interface (CONV, SCK, SDO) with no cycle latency: MSB appears on SDO's falling edge of CONV, followed by remaining bits on each SCK falling edge. The dedicated OVDD pin (1.71–5.25 V) decouples digital I/O voltage from analog supply (VDD), enabling interoperability with mixed-voltage host systems.
Key Specifications

| Temperature Range | –40°C to +85°C - qualified for industrial-grade reliability without derating. |
| Package | 8-lead TSOT-23 - 2.9 mm × 1.6 mm footprint with exposed pad for thermal performance. |
Pinout & Package
8-lead plastic TSOT-23 package with exposed thermal pad (pin 0); RoHS-compliant, lead-free finish. Requires 2.2 µF ceramic bypass capacitors on VDD, REF, and OVDD pins per datasheet layout guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog power supply input | Accepts 2.7–3.6 V or 4.75–5.25 V; powers internal reference, SAR core, and sample-and-hold. |
| REF (Pin 2) | Reference input/output | Outputs 2.048 V or 4.096 V depending on VDD; may be overdriven externally; requires 2.2 µF low-ESR bypass. |
| GND (Pin 3) | Analog ground reference | Must connect directly to solid ground plane; separates analog return path from digital noise sources. |
| AIN (Pin 4) | Analog input | Single-ended, 0 V to VREF range; 13 pF input capacitance in sample mode; draws <1 µA DC leakage. |
| OVDD (Pin 5) | Digital I/O supply | 1.71–5.25 V logic supply for SDO, SCK, CONV; enables interface with 1.8 V, 2.5 V, 3.3 V, or 5 V hosts. |
| SDO (Pin 6) | Serial data output | Three-state output; MSB-first 14-bit stream with trailing zeros; high-impedance when CONV = high. |
| SCK (Pin 7) | Serial clock input | Accepts up to 90 MHz clock; data valid on falling edge; timing-critical for t4 (9.1 ns) and t7 (1 ns) hold. |
| CONV (Pin 8) | Convert start input | Active-high edge-triggered; initiates conversion and controls SDO enable/disable and sample/hold mode. |
Key Features
| Feature | Design Value |
|---|---|
| No missing codes guarantee | Ensures monotonicity across full 14-bit range - eliminates code ambiguities in closed-loop control or calibration systems. |
| Nap mode with <50 ns wake-up | Reduces idle current to ~2 mA while preserving reference stability - enables burst-mode acquisition without settling delay. |
| Sleep mode with <1 µA typical current | Shuts down bandgap and reference buffer - ideal for ultra-low-power standby in portable instrumentation. |
| Separate OVDD supply (1.71–5.25 V) | Decouples digital interface voltage from analog supply - simplifies integration into heterogeneous voltage-domain systems. |
| Integrated 20 ppm/°C reference | Eliminates external reference IC and trimming components - reduces BOM count and PCB area in compact designs. |

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 |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1 Msps, SPI interface, 2.5 V supply only, no internal reference - requires external 2.5 V reference. | Better resolution but lower speed; suited for DC-precision applications like weigh scales where 1 Msps suffices. | Select when ENOB >13.5 is required and throughput ≤1 Msps; avoid if 2.5 Msps or internal reference is mandatory. |
| MAX11198ETE+ | 14-bit, 2 Msps, internal 2.048 V reference, 1.8–3.6 V supply, 12-lead TDFN - lacks 5 V operation and OVDD flexibility. | Lower power (12 mW @ 2 Msps) but narrower voltage range; optimized for 1.8–3.3 V battery systems only. | Select for ultra-low-voltage embedded systems where 5 V compatibility and OVDD independence are unnecessary. |
Compared with ADS8860IDRCT and MAX11198ETE+, the LTC2313ITS8-14#TRPBF uniquely combines 2.5 Msps speed, dual-supply voltage support (3 V/5 V), integrated low-drift reference, and flexible OVDD interface - making it optimal for industrial and portable instruments requiring both speed and design simplicity.

FAQ
What is the operating temperature range for the LTC2313ITS8-14#TRPBF?
The LTC2313ITS8-14#TRPBF is rated for operation from –40°C to +85°C (industrial grade). This range is explicitly specified in the Order Information table and confirmed in Absolute Maximum Ratings, ensuring reliable performance in demanding environments such as automotive under-hood or factory-floor instrumentation without derating.
Does the LTC2313ITS8-14#TRPBF require an external reference?
No, the LTC2313ITS8-14#TRPBF integrates a low-drift (20 ppm/°C max) internal reference that outputs either 2.048 V (at 2.7–3.6 V VDD) or 4.096 V (at 4.75–5.25 V VDD). External reference use is optional and only needed if higher accuracy or custom voltage scaling is required - the REF pin supports overdrive for external reference injection.
How does the nap mode function in the LTC2313ITS8-14#TRPBF?
The LTC2313ITS8-14#TRPBF automatically enters nap mode after each conversion when CONV is held high, reducing supply current to ~2 mA. Wake-up is achieved with one SCK pulse, and accurate conversion resumes within one acquisition cycle (175 ns), preserving system responsiveness without reference re-stabilization delay - unlike sleep mode which requires 1.1 ms recovery.
What logic levels are supported on the SDO, SCK, and CONV pins of the LTC2313ITS8-14#TRPBF?
Logic levels for SDO, SCK, and CONV are determined solely by the OVDD supply voltage (1.71–5.25 V), not VDD. VIH is 0.8 × OVDD and VIL is 0.2 × OVDD, enabling direct interface with 1.8 V, 2.5 V, 3.3 V, or 5 V digital systems - a key differentiator from ADCs with fixed logic thresholds.
Is the LTC2313ITS8-14#TRPBF pin-compatible with other members of the LTC2313 family?
Yes, all LTC2313-x variants (e.g., LTC2313CTS8-14#TRPBF, LTC2313HTS8-14#TRPBF) share identical 8-lead TSOT-23 pinout and footprint. Temperature grade differences (C/I/H) do not affect pin function or electrical interface - allowing drop-in replacement across grades when thermal requirements change.
