Product details
Overview
LTC2313HTS8-14#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, operating from a single 3V or 5V supply with integrated 2.048V/4.096V reference and reference buffer. It delivers 77 dB SINAD, –85 dB THD, and 77.5 dB SNR at 2.5 Msps while consuming only 14 mW at 3V - enabling high-speed, low-power data acquisition in space-constrained industrial and automotive systems.
For engineers reviewing the LTC2313HTS8-14#TRPBF datasheet, LTC2313HTS8-14#TRPBF pinout, LTC2313HTS8-14#TRPBF application, or LTC2313HTS8-14#TRPBF equivalent, key selection criteria include guaranteed 14-bit no-missing-codes performance, –40°C to 125°C extended temperature operation, nap/sleep power management modes, SPI-compatible serial interface with 1.8V–5V OVDD compatibility, and internal reference drift ≤20 ppm/°C.
Technical Context
The LTC2313HTS8-14#TRPBF implements a fully integrated SAR architecture with on-chip sample-and-hold, bandgap reference, LDO, and timing logic - eliminating external reference and buffer components. Its conversion timing is governed by an internal oscillator, requiring no external clock for core sampling; the SDO output is synchronized to externally supplied SCK up to 90 MHz.
It supports three power states: operational (4.4 mA typical at 3V), nap mode (2 mA, fast wake-up <1 conversion cycle), and sleep mode (<0.2 µA, 1.1 ms reference recovery). The analog input (AIN) accepts 0 V to VREF single-ended signals, while digital I/O levels are decoupled via dedicated OVDD (1.71 V to 5.25 V), enabling interoperability with mixed-voltage host systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 8-lead TSOT-23 (0.65 mm pitch), RoHS-compliant, moisture-sensitive level 1. Thermal resistance θJA = 195°C/W; max junction temperature = 150°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog power supply | Accepts 2.7–3.6 V or 4.75–5.25 V; powers internal SAR, reference, and LDO - requires 2.2 µF ceramic bypass to GND. |
| REF (Pin 2) | Reference input/output | Outputs 2.048 V (at 3 V supply) or 4.096 V (at 5 V supply); may be overdriven externally; bypassed with 2.2 µF low-ESR capacitor. |
| GND (Pin 3) | Analog ground | Primary return path for analog circuitry; must connect directly to solid ground plane to minimize noise coupling. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND, range 0 V to VREF; input capacitance = 13 pF in sample mode. |
| OVDD (Pin 5) | Digital I/O supply | Supplies SDO, SCK, CONV logic levels (1.71–5.25 V); enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, or 5 V controllers. |
| SDO (Pin 6) | Serial data output | Three-state MSB-first 14-bit stream; enters high-impedance when CONV = high; timing referenced to SCK falling edge. |
| SCK (Pin 7) | Serial clock input | Accepts up to 90 MHz clock; controls data shift-out timing; logic thresholds defined by OVDD voltage. |
| CONV (Pin 8) | Convert trigger | Active-high edge initiates conversion; falling edge enables SDO and places S/H into sample mode; controls nap/sleep entry via pulse count. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Conversion result appears on SDO immediately after CONV falling edge - eliminates pipeline delay for deterministic timing control. |
| Integrated reference buffer | Eliminates need for external op amp; supports 0–5 mA load; enables stable 2.048 V / 4.096 V spans with ≤20 ppm/°C drift. |
| Nap mode power management | Reduces current to ~2 mA between conversions with sub-50 ns wake-up - preserves performance while cutting average power. |
| SPI-compatible 3-wire interface | Uses only CONV, SCK, and SDO; no CS required; compatible with standard microcontroller SPI peripherals without protocol translation. |
| Wide OVDD voltage range | 1.71–5.25 V logic interface - allows seamless integration with legacy 5 V, modern 1.8 V/2.5 V FPGAs, MCUs, and DSPs. |

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, 2.5 V supply only, no internal reference - requires external REF3025 and driver amplifier. | Better DC accuracy and resolution but lower speed; suited for precision DC/low-frequency sensing rather than wideband acquisition. | Select when 16-bit resolution and integral nonlinearity <±1 LSB outweigh need for 2.5 Msps throughput and integrated reference. |
| MAX11198ETE+ | 14-bit, 2 Msps, 2.7–3.6 V supply, internal 2.048 V reference, SPI interface - lacks 5 V operation and 125°C rating. | Compatible for industrial temperature range (–40°C to 85°C) but not automotive-grade; lower max sampling rate and narrower supply range. | Choose for cost-sensitive 3 V systems where 125°C operation and 5 V compatibility are unnecessary. |

FAQ
What is the maximum sampling rate of the LTC2313HTS8-14#TRPBF?
The LTC2313HTS8-14#TRPBF supports a maximum sampling rate of 2.5 Msps, verified across its full operating temperature range (–40°C to 125°C). This rate is achieved using the internal oscillator for conversion timing, with no external clock required for core sampling. At this rate, the device delivers 77 dB SINAD and consumes 14 mW from a 3 V supply - making the LTC2313HTS8-14#TRPBF ideal for high-throughput, low-power embedded acquisition.
Does the LTC2313HTS8-14#TRPBF require an external reference voltage?
No, the LTC2313HTS8-14#TRPBF integrates a precision reference and reference buffer that automatically outputs 2.048 V when powered from 2.7–3.6 V or 4.096 V when powered from 4.75–5.25 V. The reference drift is guaranteed ≤20 ppm/°C over –40°C to 125°C. An external reference may be applied to the REF pin if higher accuracy or custom span is needed, but it is not required for standard operation of the LTC2313HTS8-14#TRPBF.
How does the nap mode function in the LTC2313HTS8-14#TRPBF?
The LTC2313HTS8-14#TRPBF enters nap mode automatically after each conversion when CONV remains high, reducing supply current to ~2 mA while preserving reference and bias circuitry. Wake-up is immediate - a new conversion can begin within one tACQ (175 ns) - unlike sleep mode, which requires 1.1 ms reference recovery. Nap mode is enabled by default and provides optimal trade-off between power savings and latency for burst-mode or variable-rate sampling in the LTC2313HTS8-14#TRPBF.
What digital interface standards does the LTC2313HTS8-14#TRPBF support?
The LTC2313HTS8-14#TRPBF features a 3-wire SPI-compatible serial interface (CONV, SCK, SDO) with no chip select required. It supports logic levels from 1.71 V to 5.25 V on OVDD, enabling direct connection to 1.8 V, 2.5 V, 3.3 V, or 5 V microcontrollers and FPGAs. SDO outputs MSB-first 14-bit data with no cycle latency, and SCK tolerates up to 90 MHz - ensuring compatibility with standard SPI peripherals without protocol translation in the LTC2313HTS8-14#TRPBF.
Is the LTC2313HTS8-14#TRPBF suitable for automotive applications?
Yes, the LTC2313HTS8-14#TRPBF is qualified for operation from –40°C to +125°C and specified across this full range for all key parameters including INL, DNL, SINAD, and reference drift. Its TSOT-23 package, robust ESD tolerance, and nap/sleep power management make it suitable for under-hood automotive sensing, battery monitoring, and engine control applications - meeting requirements for reliability and thermal resilience in the LTC2313HTS8-14#TRPBF.
