Product details
Overview
LTC2365HTS8#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1Msps successive-approximation analog-to-digital converter (SAR ADC) in an 8-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 2mA typical supply current. It features a dedicated external reference input (VREF), independent digital output supply (OVDD: 1V–VDD), SPI/MICROWIRE-compatible serial interface, and guaranteed operation from –40°C to 125°C - ideal for high-reliability industrial sensing and battery-powered instrumentation.
For engineers reviewing the LTC2365HTS8#TRPBF datasheet, LTC2365HTS8#TRPBF pinout, LTC2365HTS8#TRPBF application, or LTC2365HTS8#TRPBF equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated TS8 pin functions, application-specific value statements, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The LTC2365HTS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting full-scale input ranges from 0V to VREF (1.4V–VDD). Its serial interface requires only three wires (CS, SCK, SDO), with data output as a 16-bit frame: two leading zeros + 12-bit conversion result + two trailing zeros, MSB-first, synchronized on SCK falling edges.
It operates in two modes: active conversion (1Msps max, 1000ns throughput time) and ultra-low-power sleep mode (0.1µA typical ICC). The TS8 package enables flexible system interfacing via separate OVDD (1V–VDD) for digital output level control and VREF for precision scaling - critical for direct sensor interfacing without gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and deterministic code transitions across full temperature range (–40°C to 125°C). |
| Sampling Rate | 1Msps maximum - supports real-time acquisition of signals up to 500kHz Nyquist bandwidth with minimal latency (1000ns total throughput time). |
| SINAD / SNR | 72dB / 73dB at 1MHz input - enables >11.6 effective bits (ENOB) for high-fidelity signal digitization in noise-sensitive applications. |
| Power Consumption | 6mW at 1Msps (2mA @ 3V) - achieves industry-leading sample-rate-to-power ratio for compact, thermally constrained designs. |
| Reference Input | VREF = 1.4V to VDD - allows reduced full-scale spans (e.g., 1.4V) for direct connection to low-output sensors while maintaining 342µV LSB resolution. |
| Digital I/O Supply | OVDD = 1V to VDD - permits interoperability with 1.8V, 2.5V, or 3V logic families without level shifters. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial motor control, and downhole instrumentation environments. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (3.0mm × 1.7mm × 0.8mm), RoHS-compliant, lead-free finish, tape-and-reel (2500 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive analog supply | 2.35V–3.6V main power rail; defines internal biasing and analog core operation; requires 10µF ceramic bypass to GND. |
| VREF (Pin 2) | External reference input | Set full-scale range (0V to VREF); supports 1.4V–VDD; bypass with 4.7µF ceramic; enables precision scaling for sensor interfaces. |
| 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, high-impedance input (±1µA leakage); accepts 0V to VREF; optimized for direct transducer connection. |
| OVDD (Pin 5) | Digital output supply | Controls SDO output voltage swing (1V–VDD); decoupled with 4.7µF ceramic; enables mixed-voltage system interfacing. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first output; drives 16-bit frame (00 + 12-bit result + 00); Hi-Z when CS = HIGH. |
| SCK (Pin 7) | Serial clock input | Accepts 0.5–16MHz clock; data valid on falling edge; timing-critical for synchronization with host controller. |
| CS (Pin 8) | Chip select input | Active-low conversion trigger; falling edge initiates sampling and enables SDO; frames entire 16-bit data transfer. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion completes within fixed 1000ns throughput time - eliminates pipeline delay for deterministic real-time control loops. |
| Sleep mode (0.1µA) | Reduces quiescent current by >99% vs active mode - extends battery life in intermittent-sampling systems like portable diagnostics. |
| Flexible reference & output supplies | VREF and OVDD pins allow independent optimization of analog accuracy and digital compatibility - avoids costly external level shifters or regulators. |
| High dynamic range (72dB SINAD) | Preserves signal integrity for low-amplitude, high-frequency inputs (e.g., ultrasound preamps, vibration sensors) without post-processing correction. |
| Guaranteed operation to 125°C | Validated performance over full industrial/automotive junction temperature range - eliminates derating calculations for thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 12-bit, 200ksps, 2.7–5.25V supply, SO-8 package, no OVDD/VREF separation. | Limited to lower sampling rates and wider supply range; lacks independent OVDD for mixed-voltage interfacing. | Select when cost sensitivity outweighs speed/power needs and system uses 3.3V or 5V logic exclusively. |
| MAX11100ETE+ | 12-bit, 1Msps, 2.7–3.6V supply, 12-lead TQFN, integrated reference, no OVDD pin. | Includes internal 2.048V reference but no external VREF or OVDD flexibility; larger footprint than TSOT-23. | Choose when board space permits larger package and internal reference simplifies layout, but external scaling is not required. |
Compared with ADS7822U and MAX11100ETE+, the LTC2365HTS8#TRPBF uniquely combines 1Msps speed, ultra-low 2mA supply current, TSOT-23 miniaturization, and dual-supply flexibility (VREF + OVDD) - making it optimal for space-constrained, multi-voltage, high-temperature embedded systems where precision and power efficiency are co-prioritized.

FAQ
What is the maximum sampling rate supported by the LTC2365HTS8#TRPBF?
The LTC2365HTS8#TRPBF supports a maximum sampling rate of 1Msps, with guaranteed timing performance across its full operating temperature range (–40°C to 125°C). This is achieved using an SCK frequency up to 16MHz and a fixed 1000ns throughput time (tTHROUGHPUT), enabling deterministic real-time acquisition for control and monitoring applications.
Does the LTC2365HTS8#TRPBF require an external reference voltage?
Yes - the LTC2365HTS8#TRPBF requires an external reference voltage applied to the VREF pin (Pin 2). VREF sets the full-scale input range (0V to VREF) and can be configured from 1.4V up to VDD (2.35V–3.6V), allowing precise scaling for low-output sensors without additional gain stages.
Can the LTC2365HTS8#TRPBF interface directly with a 1.8V microcontroller?
Yes - the LTC2365HTS8#TRPBF supports direct interfacing with 1.8V logic via its OVDD pin (Pin 5), which controls the SDO output voltage swing. When OVDD = 1.8V, the SDO output levels comply with 1.8V logic thresholds, eliminating the need for external level-shifting circuitry.
What is the power consumption of the LTC2365HTS8#TRPBF in sleep mode?
In sleep mode, the LTC2365HTS8#TRPBF draws only 0.1µA typical supply current (IDD), reducing power by >99% compared to active operation. This ultra-low quiescent current is enabled via the CS pin and is fully specified over the –40°C to 125°C temperature range.
Is the LTC2365HTS8#TRPBF pin-compatible with the LTC2366HTS8#TRPBF?
No - while both share the same TSOT-23-8 package and pinout, the LTC2365HTS8#TRPBF (1Msps) and LTC2366HTS8#TRPBF (3Msps) differ in maximum sampling rate, SCK frequency limits (16MHz vs 48MHz), and AC performance specifications (e.g., THD at 1MHz is –86dB for LTC2365 vs –80dB for LTC2366). They are functionally similar but not drop-in replacements.
