Product details
Overview
LTC2365HS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1Msps 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 no data latency, 73dB SNR at 1MHz input, 72.8dB SINAD, and –86.1dB THD - optimized for compact, battery-powered sensor interface and portable medical systems.
For engineers reviewing the LTC2365HS6#TRMPBF datasheet, LTC2365HS6#TRMPBF pinout, LTC2365HS6#TRMPBF application, or LTC2365HS6#TRMPBF equivalent, this page delivers verified specifications, thermal-grade packaging details (–40°C to 125°C), real-world timing behavior, and validated alternative options for high-speed, low-power sampling in space-constrained designs.
Technical Context
The LTC2365HS6#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting full-scale input ranges of 0V to VDD without external reference. Its serial interface uses SPI/MICROWIRE-compatible 3-wire signaling (CS, SCK, SDO), with MSB-first 16-bit frame format (two leading zeros + 12 data bits + two trailing zeros) and guaranteed operation up to 16MHz SCK frequency.
It achieves 1Msps throughput via 14–16 SCK cycles per conversion, with acquisition time of 181.5ns and conversion time of 818.5ns. Sleep mode reduces supply current to 0.1µA typical, enabling rapid wake-up (<1µs power-up time) while maintaining full specification compliance across its extended temperature range.
Key Specifications

Pinout & Package
Package: 6-lead Plastic TSOT-23, 1.6mm × 1.6mm × 0.55mm profile, exposed pad optional, rated for –40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND (Pin 2) | Analog Ground Reference | Low-impedance return path for analog and digital sections; must connect directly to solid ground plane. |
| AIN (Pin 3) | Analog Input | Single-ended, high-impedance (20pF capacitance) input referenced to GND; accepts 0V to VDD full-scale signals. |
| SCK (Pin 4) | Serial Clock Input | Edge-triggered clock (≤16MHz) controlling conversion timing and data shift-out; falling edge clocks data. |
| SDO (Pin 5) | Serial Data Output | Three-state, MSB-first output delivering 16-bit frame (00 + 12-bit code + 00); swing tied to VDD voltage. |
| CS (Pin 6) | Chip Select Input | Active-low signal initiating conversion on falling edge; frames serial data transfer and controls SDO enable/disable. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Output reflects most recent sampled value immediately after conversion completes - critical for closed-loop control timing. |
| Sleep mode (0.1µA) | Reduces quiescent current by >99.9% during idle periods, extending battery life in intermittent-sampling applications. |
| Single-supply operation | Eliminates need for dual-rail supplies or external reference ICs, simplifying PCB layout and BOM count. |

FAQ
What is the maximum sampling rate supported by the LTC2365HS6#TRMPBF?
The LTC2365HS6#TRMPBF supports a maximum sampling rate of 1Msps, achieved using a 16MHz SCK clock with 14–16 clock cycles per conversion. This rate is fully characterized and guaranteed over the –40°C to 125°C operating temperature range, with no performance degradation at high ambient temperatures.
Does the LTC2365HS6#TRMPBF require an external reference voltage?
No, the LTC2365HS6#TRMPBF does not require an external reference. In the S6 package configuration, it uses VDD as the reference source, providing a full-scale input range of 0V to VDD (2.35V–3.6V). This eliminates external reference components and simplifies system-level calibration.
How does the sleep mode function on the LTC2365HS6#TRMPBF?
The LTC2365HS6#TRMPBF enters sleep mode when CS remains high and SCK is held static (0V or VDD), reducing supply current to 0.1µA typical. Wake-up occurs on the first falling edge of CS, with full operational readiness achieved within 333ns - enabling rapid, deterministic response in duty-cycled sensing applications.
What are the absolute maximum ratings for the analog input pin (AIN) of the LTC2365HS6#TRMPBF?
The AIN pin of the LTC2365HS6#TRMPBF has an absolute maximum rating of –0.3V to (VDD + 0.3V). Internal clamping diodes protect against overvoltage, allowing safe handling of transient currents exceeding 100mA without latchup - a key reliability feature for noisy industrial environments.
Is the LTC2365HS6#TRMPBF pin-compatible with other members of the LTC236x family?
The LTC2365HS6#TRMPBF shares identical pinout and footprint with the LTC2366HS6#TRMPBF (3Msps variant) and all other S6-package variants (e.g., LTC2365IS6#TRMPBF). However, it is not pin-compatible with TS8-package versions due to differing pin count and VREF/OVDD pin assignments.
