Product details
Overview
LTC2365HTS8#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1 Msps 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 dedicated VREF and OVDD pins. It delivers 73 dB SNR, –86 dB THD at 1 MHz input, 0.34 LSB RMS transition noise, and 0.1 µA sleep current, enabling high-fidelity signal acquisition in space-constrained, battery-powered instrumentation.
For engineers reviewing the LTC2365HTS8#TRMPBF datasheet, LTC2365HTS8#TRMPBF pinout, LTC2365HTS8#TRMPBF application, or LTC2365HTS8#TRMPBF equivalent, this page provides verified technical context, validated pin functions, confirmed thermal grade (–40°C to 125°C), real-world application mappings, and two rigorously cross-checked alternative parts - all derived from official Linear Technology documentation and Analog Devices product specifications.
Technical Context
The LTC2365HTS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting single-ended analog inputs referenced to GND with full-scale range 0 V to VREF (1.4 V to VDD). Its serial interface uses SPI/MICROWIRE-compatible 3-wire timing with MSB-first 16-bit frame (two leading zeros + 12 data bits + two trailing zeros), no data latency, and configurable SDO output swing via OVDD (1 V to VDD).
It operates across –40°C to 125°C with guaranteed performance including ±0.25 LSB integral linearity error, ±3.5 LSB total unadjusted error (TS8 package), and full-power bandwidth of 30 MHz (–3 dB). Sleep mode activation reduces supply current to 0.1 µA typical, and power-up time from sleep is 333 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - ensures monotonic transfer function for precision control and measurement. |
| Sampling Rate | 1 Msps maximum - supports real-time digitization of signals up to 500 kHz Nyquist bandwidth. |
| SNR / SINAD | 73 dB / 72.8 dB at 1 MHz input - enables >11.8 ENOB for high-fidelity sensor and medical signal capture. |
| THD | –86.1 dB at 1 MHz input - minimizes harmonic contamination in spectral analysis and communication systems. |
| Supply Current | 2 mA typical at 1 Msps - achieves 6 mW power dissipation at 3 V, critical for thermally constrained designs. |
| Sleep Current | 0.1 µA typical - extends battery life in intermittent-sampling applications like portable diagnostics. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive, industrial motor control, and avionics environments. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (0.65 mm pitch, 2.9 mm × 1.6 mm footprint), moisture sensitivity level 1, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply input | 2.35 V–3.6 V main supply; defines internal biasing and sets upper limit for VREF; requires 10 µF ceramic bypass to GND. |
| VREF (Pin 2) | External reference input | Defines full-scale analog input range (0 V to VREF); supports 1.4 V–VDD range; requires 4.7 µF ceramic bypass. |
| GND (Pin 3) | Analog ground reference | Common return for analog circuitry; must connect directly to solid ground plane to minimize noise coupling. |
| AIN (Pin 4) | Analog input terminal | Single-ended input referenced to GND; accepts 0 V to VREF; high-impedance (±1 µA leakage) for direct sensor interfacing. |
| OVDD (Pin 5) | Digital output driver supply | Sets SDO logic swing (1 V–VDD); enables interoperability with 1.8 V/2.5 V/3.3 V digital systems without level shifters. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first output delivering 16-bit frame (00 + 12-bit code + 00); Hi-Z when CS = HIGH. |
| SCK (Pin 7) | Serial clock input | Edge-triggered clock (max 16 MHz); falling edge clocks out data; timing-critical for throughput consistency. |
| CS (Pin 8) | Chip select input | Active-low conversion start and frame sync; falling edge initiates sampling and enables SDO output. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated VREF and OVDD pins | Enables flexible full-scale scaling (down to 1.4 V) and independent digital I/O voltage control for mixed-supply systems. |
| No data latency | Delivers first valid conversion result within one sampling period - essential for closed-loop real-time control. |
| 0.1 µA sleep mode current | Reduces average system power by >99% during idle intervals, extending operational lifetime in energy-harvesting nodes. |
| High dynamic range sample-and-hold | Supports 73 dB SNR and 30 MHz full-power bandwidth - captures fast transients without aliasing or distortion. |
| Guaranteed operation to 125°C | Validated performance over extended temperature range eliminates derating concerns in harsh-environment deployments. |

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, 200 kSPS, 2.7–5.25 V supply, no dedicated VREF/OVDD pins, SO-8 package | Lower speed and fixed 3.3/5 V I/O compatibility; lacks TSOT-23 footprint and extended temperature rating | Select when cost-sensitive, lower-throughput industrial sensing is sufficient and board space is not constrained. |
| MAX11100ETE+ | 12-bit, 1 Msps, 2.7–3.6 V supply, internal reference only, 16-pin TQFN, –40°C to 85°C | Internal reference limits full-scale flexibility; 85°C max temp excludes under-hood or high-temp industrial use | Choose for simplified layout where external reference isn't needed and ambient temperature stays below 85°C. |
Compared with ADS7822U and MAX11100ETE+, the LTC2365HTS8#TRMPBF uniquely combines 1 Msps throughput, –40°C to 125°C operation, TSOT-23 miniaturization, and dual-supply flexibility (VREF + OVDD), making it the only option qualified for compact, high-reliability, wide-temperature embedded measurement.

FAQ
What is the maximum sampling rate supported by the LTC2365HTS8#TRMPBF?
The LTC2365HTS8#TRMPBF supports a maximum sampling rate of 1 Msps, as specified in its datasheet and validated across the full –40°C to 125°C operating temperature range. This rate is achieved using a maximum 16 MHz SCK frequency and requires 14 SCK cycles per conversion. The device maintains guaranteed AC performance-including 72.8 dB SINAD and –86.1 dB THD-at this rate with a 1 MHz input signal.
Does the LTC2365HTS8#TRMPBF require an external reference voltage?
Yes, the LTC2365HTS8#TRMPBF requires an external reference voltage applied to the VREF pin (Pin 2). Its analog input range is 0 V to VREF, and VREF must be between 1.4 V and VDD (2.35 V–3.6 V). Unlike the S6-package variants, the TS8 package does not use VDD as the reference, enabling precise full-scale scaling and improved accuracy when paired with a stable external reference.
How does the OVDD pin on the LTC2365HTS8#TRMPBF improve system design?
The OVDD pin (Pin 5) on the LTC2365HTS8#TRMPBF independently powers the SDO output driver, allowing logic-level compatibility with 1.8 V, 2.5 V, or 3.3 V digital systems without external level shifters. This decoupling from VDD simplifies mixed-voltage board design, reduces signal integrity risk, and avoids contention when interfacing with low-voltage microcontrollers or FPGAs-directly enhancing interoperability in modern embedded architectures.
What is the guaranteed operating temperature range for the LTC2365HTS8#TRMPBF?
The LTC2365HTS8#TRMPBF is rated for continuous operation from –40°C to 125°C, as indicated by the "H" grade suffix and confirmed in the Absolute Maximum Ratings and Operating Temperature Range tables of the official datasheet. All key specifications-including linearity, SNR, THD, and supply current-are guaranteed across this full range, making it suitable for under-hood automotive, industrial motor drives, and aerospace applications.
Can the LTC2365HTS8#TRMPBF operate in sleep mode, and what is its wake-up time?
Yes, the LTC2365HTS8#TRMPBF supports a low-power sleep mode with 0.1 µA typical supply current. Wake-up is initiated by pulling CS low, and the device achieves full operational readiness in 333 ns-verified in the Timing Characteristics table. This rapid recovery enables burst-mode sampling strategies in battery-powered equipment, minimizing active time while preserving responsiveness for event-triggered measurements.
