Product details
Overview
LTC2365HS6#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1 Msps successive-approximation analog-to-digital converter (SAR ADC) in a 6-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 2mA typical supply current. It features a high-impedance single-ended analog input (0V to VDD), no data latency, and guaranteed operation from –40°C to 125°C - ideal for battery-powered instrumentation and high-reliability industrial sensing.
For engineers reviewing the LTC2365HS6#TRPBF datasheet, LTC2365HS6#TRPBF pinout, LTC2365HS6#TRPBF application, or LTC2365HS6#TRPBF equivalent, this page delivers verified electrical specs, thermal-grade packaging context, SPI/MICROWIRE-compatible timing behavior, and real-world design implications for low-power, high-speed sampling systems.
Technical Context
The LTC2365HS6#TRPBF uses an internal sample-and-hold with 0.34 LSB RMS transition noise and aperture jitter of 0.3 ns, enabling accurate digitization of signals up to 2.5 MHz full-linear bandwidth. Its SAR architecture delivers 72 dB SINAD at 1 Msps with 1 MHz input, and supports sleep mode with 0.1 µA typical quiescent current.
Unlike the TS8 variant, the S6 package ties reference to VDD - eliminating external reference components but fixing full-scale range to 0V–VDD. Serial interface timing requires minimum 0.5 MHz SCK and supports 14-cycle conversion (12 data bits + 2 leading zeros), with SDO output swing referenced directly to VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and deterministic code mapping across full temperature range. |
| Sampling Rate | 1 Msps maximum - enables real-time capture of signals up to Nyquist frequency of 500 kHz without undersampling artifacts. |
| SINAD | 72 dB at 1 MHz input - supports >11.7 effective bits for precision measurement in noisy environments. |
| Supply Current | 2 mA at 1 Msps, 0.1 µA in sleep mode - reduces average power in duty-cycled sensor interfaces by >99%. |
| Analog Input Range | 0 V to VDD (2.35–3.6 V) - eliminates need for level-shifting or external reference when powered from same rail as signal source. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and downhole sensing applications. |
| Package | 6-lead TSOT-23 (2.9 mm × 1.6 mm × 0.8 mm) - enables ultra-compact PCB layouts with minimal parasitic capacitance on AIN and SDO lines. |
Pinout & Package
6-lead plastic TSOT-23 package with exposed pad (not electrically connected); requires solid ground plane and 10 µF ceramic bypass capacitor on VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and internal reference | Defines full-scale analog input range (0V to VDD); must be bypassed to GND with ≥10 µF ceramic capacitor. |
| GND (Pin 2) | Analog and digital ground reference | Single-point connection to solid ground plane required to minimize noise coupling into sample-and-hold node. |
| AIN (Pin 3) | Analog input | High-impedance (±1 µA leakage), single-ended input referenced to GND; accepts DC-coupled signals up to VDD. |
| SCK (Pin 4) | Serial clock input | Edge-triggered falling-edge clock; controls conversion timing and serial data shift-out; max 16 MHz. |
| SDO (Pin 5) | Three-state serial data output | MSB-first 16-bit frame (2 leading zeros + 12 data bits + 2 trailing zeros); output swing = VDD. |
| CS (Pin 6) | Chip select input | Active-low signal initiating conversion on falling edge; frames serial data transfer and enables SDO. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after final SCK edge - enables deterministic real-time control loops. |
| Sleep mode | 0.1 µA typical supply current with CS high - allows microcontroller to wake ADC only before sampling, minimizing system-level power. |
| Single-supply operation | 2.35V–3.6V VDD range - compatible with Li-ion, 3.3V logic, and wide-input DC/DC converters without LDO post-regulation. |
| High dynamic range | 73 dB SNR and –86 dB THD at 1 MHz - preserves signal fidelity in vibration monitoring and audio-band sensor conditioning. |
| Robust input protection | Clamped analog input handles ±100 mA transient overvoltage without latch-up - reduces need for external TVS diodes. |
Applications
| Industrial Process Monitoring | Automotive Battery Management |

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, 2.7–5.25V supply, SO-8 package; higher power (1.2 mW), lower speed, no sleep mode. | Not rated for >85°C; unsuitable for under-hood or industrial ambient use. | Select only for cost-sensitive, non-extended-temperature designs where 200 ksps suffices. |
| MAX11166ETE+ | 12-bit, 1 Msps, –40°C to +125°C, 10-lead TDFN; requires external reference and separate DVDD/AVDD rails. | Higher layout complexity due to dual supplies and reference decoupling; larger footprint than TSOT-23. | Prefer when system already uses precision external reference or requires independent analog/digital supply domains. |
Compared with ADS7822U and MAX11166ETE+, the LTC2365HS6#TRPBF offers superior thermal rating, integrated VDD-referenced operation, and smallest PCB footprint - making it optimal for space-constrained, high-temperature embedded systems requiring minimal BOM count.

FAQ
What is the maximum sampling rate of the LTC2365HS6#TRPBF?
The LTC2365HS6#TRPBF has a maximum sampling rate of 1 Msps, confirmed across its full –40°C to +125°C operating range. This rate is achieved using a 16 MHz SCK clock with 14-cycle conversion timing, and is guaranteed in the datasheet's timing characteristics table under fSMPL(MAX) parameter.
Does the LTC2365HS6#TRPBF require an external reference voltage?
No, the LTC2365HS6#TRPBF does not require an external reference. As a 6-lead TSOT-23 (S6) variant, it uses VDD as the internal reference, setting the full-scale analog input range to 0V to VDD. This eliminates external reference components and simplifies layout compared to the 8-lead TS8 variants like LTC2365HTS8#TRPBF.
What is the sleep mode current consumption of the LTC2365HS6#TRPBF?
The LTC2365HS6#TRPBF draws 0.1 µA typical supply current in sleep mode, as specified in the Power Requirement section of the datasheet under IDD (Sleep Mode) at –40°C to 85°C. This ultra-low quiescent current enables aggressive duty cycling in battery-powered applications without compromising wake-up latency.
Can the LTC2365HS6#TRPBF interface directly with a 1.8V microcontroller?
No - the LTC2365HS6#TRPBF's SDO output swing is referenced to VDD, and its minimum VDD is 2.35V. For reliable 1.8V logic compatibility, use the TS8-package variant (e.g., LTC2365HTS8#TRPBF), which provides a dedicated OVDD pin to set SDO output voltage independently from VDD.
Is the LTC2365HS6#TRPBF pin-compatible with other members of the LTC2365/LTC2366 family?
The LTC2365HS6#TRPBF shares identical pinout and footprint with all other S6-package variants (e.g., LTC2365CS6#TRPBF, LTC2365IS6#TRPBF), differing only in temperature grade. However, it is not pin-compatible with TS8-package devices due to different pin count, function allocation (e.g., no VREF or OVDD pins), and package dimensions.
