Product details
Overview
LTC2365IS6#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. It delivers 73dB SNR, 72dB SINAD at 1Msps, –86dB THD, and draws only 2mA typical supply current. Its high-impedance single-ended analog input (0V to VDD), no data latency, and sleep mode (0.1µA) make it ideal for battery-powered sensor interfaces and compact data acquisition systems.
For engineers reviewing the LTC2365IS6#TRMPBF datasheet, LTC2365IS6#TRMPBF pinout, LTC2365IS6#TRMPBF application, or LTC2365IS6#TRMPBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, TSOT-23-6 footprint compatibility, 12-bit resolution with ±0.25 LSB INL, and SPI/MICROWIRE-compatible serial interface timing at up to 16MHz SCK.
Technical Context
The LTC2365IS6#TRMPBF implements a switched-capacitor SAR architecture with an integrated sample-and-hold circuit referenced directly to VDD. Its analog input range is fixed at 0V to VDD (no external reference), eliminating VREF and OVDD pins-unlike the 8-lead TS8 variant-and simplifying layout for space-constrained designs.
It uses a 3-wire SPI-compatible serial interface (CS, SCK, SDO) with MSB-first 16-cycle frame (two leading zeros + 12 data bits + two trailing zeros). Conversion is initiated on CS falling edge; SDO transitions on SCK falling edges, and output returns to Hi-Z after CS rising or 16th SCK falling edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and full code coverage for precision measurement. |
| Sampling Rate | 1Msps maximum - supports real-time digitization of signals up to 500kHz Nyquist bandwidth. |
| SNR / SINAD | 73dB / 72.8dB at 1MHz input - enables >11.6 ENOB for high-fidelity signal capture in noise-sensitive applications. |
| Supply Current | 2mA typical at 1Msps - achieves 6mW power dissipation at 3V, enabling ultra-low-power portable instrumentation. |
| Integral Linearity | ±0.25 LSB max over temperature - ensures <0.006% full-scale error without calibration in industrial sensing. |
| Sleep Current | 0.1µA typical - reduces standby power by 4 orders of magnitude versus active mode for duty-cycled systems. |
| Operating Temp | –40°C to +85°C - qualified for automotive cabin, industrial control, and outdoor embedded environments. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (0.95mm × 1.65mm × 0.55mm height), lead-free, RoHS-compliant, thermal resistance θJA = 250°C/W.
| 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 with 10µF ceramic + 0.1µF ceramic to GND. |
| GND (Pin 2) | Analog and digital ground reference | Single-point connection to solid ground plane required to minimize noise coupling into sample-and-hold. |
| AIN (Pin 3) | Analog input | High-impedance (20pF), single-ended input referenced to GND; accepts 0V to VDD range without external gain stage. |
| SCK (Pin 4) | Serial clock input | Accepts up to 16MHz CMOS-level clock; falling edge clocks out each bit of 16-bit frame (MSB first). |
| SDO (Pin 5) | Three-state serial data output | Drives logic levels compatible with VDD; outputs 16-bit frame (00 + 12-bit data + 00) with Hi-Z when CS is high. |
| CS (Pin 6) | Chip select input | Active-low signal that initiates conversion on falling edge and frames serial data transfer; rising edge terminates output. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after final SCK edge - eliminates pipeline delay for real-time control loops. |
| Single-supply operation | 2.35V–3.6V VDD powers analog core, digital interface, and internal reference - removes need for dual supplies or external references. |
| Low-power sleep mode | 0.1µA quiescent current with full state retention - enables microcontroller-gated sampling without re-initialization overhead. |
| High-speed serial interface | 16MHz SCK support with guaranteed timing margins - allows direct interfacing to FPGA I/O banks or MCU SPI peripherals without level shifters. |
| Robust input protection | Clamped analog input tolerates –0.05V to VDD+0.05V - prevents latch-up during transient overvoltage events in harsh environments. |

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, 250ksps, 2.7–5.25V supply, SO-8 package - slower, wider voltage range, larger footprint. | Lower throughput limits use in fast transient capture; SO-8 requires more PCB area than TSOT-23-6. | Select when legacy 5V systems or higher supply margin is required; not suitable for 1Msps or space-constrained designs. |
| MAX11100ETT+ | 12-bit, 1Msps, 2.7–3.6V supply, 6-pin TDFN - identical speed but different pinout and no sleep mode (3µA standby). | Higher standby current increases average power in duty-cycled systems; TDFN thermal performance differs from TSOT-23. | Choose for TDFN-adopting platforms where sleep mode is unnecessary; verify thermal derating at 85°C ambient. |
Compared with ADS7822U and MAX11100ETT+, the LTC2365IS6#TRMPBF uniquely combines 1Msps throughput, 0.1µA sleep current, and TSOT-23-6 packaging - delivering the highest sample-rate-per-milliwatt ratio and smallest board footprint among verified alternatives.

FAQ
What is the maximum sampling rate supported by the LTC2365IS6#TRMPBF?
The LTC2365IS6#TRMPBF supports a maximum sampling rate of 1Msps, achieved with a 16MHz SCK clock and 14-cycle conversion timing. This rate is fully characterized and guaranteed over the –40°C to +85°C operating temperature range, with throughput time of 1000ns and no data latency in the serial output stream.
Does the LTC2365IS6#TRMPBF require an external reference voltage?
No, the LTC2365IS6#TRMPBF does not require an external reference. It uses its VDD supply as the internal reference, resulting in a 0V to VDD analog input range. This eliminates the need for external reference components, simplifies design, and reduces system cost - unlike the 8-lead TS8 variants (e.g., LTC2365ITS8#TRMPBF) which support dedicated VREF and OVDD pins.
What is the analog input impedance and leakage current of the LTC2365IS6#TRMPBF?
The LTC2365IS6#TRMPBF features a high-impedance analog input with 20pF capacitance between conversions and ±1µA maximum leakage current (at CS = high). This allows direct connection to high-output-impedance sensors such as thermistors or piezoelectric elements without buffer amplifiers, preserving signal integrity and minimizing power consumption in the signal chain.
How does the sleep mode of the LTC2365IS6#TRMPBF operate, and what is its wake-up time?
The LTC2365IS6#TRMPBF enters sleep mode when CS remains high and SCK is held static; it draws 0.1µA typical supply current. Wake-up occurs on the falling edge of CS, with power-up time from sleep mode specified at 1000ns maximum. This enables rapid, deterministic acquisition bursts synchronized to host processor activity without initialization delays.
Is the LTC2365IS6#TRMPBF pin-compatible with other members of the LTC2365/LTC2366 family?
The LTC2365IS6#TRMPBF shares the same 6-lead TSOT-23 pinout with all S6-package variants (e.g., LTC2365CS6#TRMPBF, LTC2365HS6#TRMPBF), but is not pin-compatible with TS8-package devices (e.g., LTC2365ITS8#TRMPBF) due to differing pin count, functions (VREF, OVDD), and layout. Temperature grade differences (I vs C vs H) do not affect pinout or electrical compatibility.
