Product details
Overview
LTC2360IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 100ksps successive-approximation ADC in a 6-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 0.5mA typical supply current at full rate and 0.1μA sleep current. It features single-ended analog input (0V to VDD), SPI/MICROWIRE-compatible serial interface, no data latency, and guaranteed operation from –40°C to +85°C. It targets ultra-low-power sensor digitization in portable instrumentation and battery-powered monitoring systems.
For engineers reviewing the LTC2360IS6#TRMPBF datasheet, LTC2360IS6#TRMPBF pinout, LTC2360IS6#TRMPBF application, or LTC2360IS6#TRMPBF equivalent, key selection criteria include its 12-bit resolution with ±1 LSB INL, 73dB SNR at 49kHz, 100ksps throughput with 10μs minimum throughput time, and direct compatibility with 3V microcontrollers via 3-wire serial I/O without external reference or level-shifting.
Technical Context
The LTC2360IS6#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to enforce precise 100ksps sampling. Its analog input is referenced directly to VDD (no external VREF required), simplifying layout for space-constrained designs.
Serial communication follows SPI timing: CONV rising edge initiates conversion; CONV falling edge enables SDO and clocks out 12-bit MSB-first data on SCK falling edges; trailing zeros follow valid bits. Sleep mode activates automatically after conversion when CONV remains high, reducing IDD to 0.1μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and full 4096-code range for precision measurement. |
| Sampling Rate | 100ksps maximum - supports real-time acquisition of signals up to 49kHz Nyquist bandwidth with 73dB SNR. |
| Supply Current | 0.5mA typ at 100ksps; 0.1μA typ in sleep - enables multi-year battery life in duty-cycled sensor nodes. |
| INL / DNL | ±1 LSB max INL, ±1 LSB max DNL - ensures <0.025% end-point linearity error for calibrated transducer interfaces. |
| SNR / SINAD | 73dB SNR, 72dB SINAD at fIN=49kHz - delivers >11.8 ENOB for high-fidelity signal capture in noisy environments. |
| Analog Input Range | 0V to VDD (2.35V–3.6V) - eliminates need for external reference or gain stage when interfacing with 3V sensors. |
| Operating Temp | –40°C to +85°C - qualified for industrial and automotive under-hood sensing applications without derating. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 2.9mm × 1.6mm × 0.8mm, moisture sensitivity level 1, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and analog reference | Supplies core logic and defines full-scale input range (0V to VDD); requires 2.2μF ceramic bypass to GND. |
| GND (Pin 2) | Analog and digital ground | Single ground connection; must tie directly to solid ground plane to minimize noise coupling into analog input. |
| AIN (Pin 3) | Analog input | High-impedance (±1μA leakage), single-ended input referenced to GND; accepts 0V to VDD range without attenuation. |
| SCK (Pin 4) | Serial clock input | Accepts up to 10MHz clock; data latched on rising edge, SDO transitions on falling edge per SPI convention. |
| SDO (Pin 5) | Three-state serial data output | Outputs 12-bit conversion result MSB-first; enters Hi-Z when CONV = high; compatible with 1.8V–3.6V logic families. |
| CONV (Pin 6) | Convert control input | Active-high signal; rising edge starts conversion, falling edge enables SDO and initiates data readout; controls sleep/wake state. |
Key Features
| Feature | Design Value |
|---|---|
| No external reference required | VDD serves as reference - reduces BOM count and PCB area; eliminates reference drift and matching errors. |
| Automatic sleep mode | IDD drops to 0.1μA after conversion - cuts average power by >99% in low-duty-cycle sampling (e.g., 10s interval). |
| No data latency | Conversion completes within 10μs (tTHROUGHPUT) - enables deterministic real-time control loops with sub-100μs response. |
| High-impedance analog input | ±1μA input leakage, 4pF input capacitance - allows direct connection to high-Z sources (e.g., thermistors, RTDs) without buffer op-amps. |
| Guaranteed operation to +85°C | Specified over full industrial temperature range - avoids thermal derating or system-level cooling in enclosed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, low-power SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 12-bit, 200ksps, 2.7–5.25V supply, requires external reference; 1.25mW at 100ksps vs. 1.5mW for LTC2360IS6#TRMPBF. | Needs external 2.5V reference and level-shifting for 3V systems; larger SO-8 package increases board area. | Select when higher sampling rate (200ksps) is required and external reference is already present in design. |
| MAX11100ETE+ | 12-bit, 100ksps, 2.7–3.6V supply, internal reference option; 0.95mW at 100ksps; 10-lead TDFN package. | Includes optional internal 2.048V reference but adds 100ppm/°C drift; requires decoupling for reference pin. | Select when reference flexibility (internal/external) is prioritized over minimal footprint and lowest sleep current. |
Compared with ADS7822U and MAX11100ETE+, the LTC2360IS6#TRMPBF offers the smallest form factor (TSOT-23), lowest sleep current (0.1μA), and simplest interface (VDD-referenced, no reference management), making it optimal for size- and battery-limited embedded systems where 100ksps is sufficient.

FAQ
What is the maximum sampling rate of the LTC2360IS6#TRMPBF?
The LTC2360IS6#TRMPBF has a maximum sampling rate of 100ksps, corresponding to a minimum throughput time of 10μs. This rate is fixed by the internal oscillator and does not require external clocking. At lower rates, supply current scales down automatically due to built-in sleep mode activation after each conversion, enabling adaptive power optimization in burst-mode applications.
Does the LTC2360IS6#TRMPBF require an external voltage reference?
No, the LTC2360IS6#TRMPBF does not require an external voltage reference. It uses VDD as the reference source, establishing a 0V to VDD analog input range. This eliminates the need for a separate reference IC, reduces BOM cost and PCB area, and avoids reference-related drift or mismatch errors-making it ideal for compact, low-component-count sensor interfaces.
What is the guaranteed operating temperature range for the LTC2360IS6#TRMPBF?
The LTC2360IS6#TRMPBF is specified for operation from –40°C to +85°C (Industrial grade). This range is fully characterized and guaranteed across all electrical parameters including INL, SNR, and supply current. The device maintains 73dB SNR and ±1 LSB INL throughout this range, supporting reliable deployment in uncontrolled environments such as factory floors or vehicle cabins.
How does the serial interface of the LTC2360IS6#TRMPBF work?
The LTC2360IS6#TRMPBF uses a 3-wire SPI/MICROWIRE-compatible interface: CONV initiates conversion on its rising edge and enables SDO on its falling edge; SCK clocks data out on falling edges; SDO outputs 12-bit MSB-first data followed by trailing zeros. No CS pin is needed-the interface is inherently frame-synchronized by CONV timing, simplifying microcontroller GPIO usage and eliminating bus contention risks.
What is the sleep current of the LTC2360IS6#TRMPBF and how is it activated?
The LTC2360IS6#TRMPBF draws 0.1μA typical supply current in sleep mode, activated automatically when CONV remains high after conversion completion. During sleep, all bias currents are shut down and only leakage paths remain active. Waking occurs on the falling edge of CONV, with full acquisition completed within 2μs (tACQ), enabling rapid, deterministic wake-and-sample sequences for energy-efficient sensing.
