Product details
Overview
LTC2366ITS8#TRMPBF from Analog Devices (formerly Linear Technology) is a 3Msps, 12-bit successive-approximation analog-to-digital converter (SAR ADC) in an 8-lead TSOT-23 package. It operates from a single 2.35V–3.6V supply, draws 2.6mA at full speed, delivers 72dB SINAD and –80.3dB THD at 994kHz input, and features dedicated VREF and OVDD pins for flexible reference and digital output voltage control - ideal for battery-powered instrumentation and compact sensor interfaces.
For engineers reviewing the LTC2366ITS8#TRMPBF datasheet, LTC2366ITS8#TRMPBF pinout, LTC2366ITS8#TRMPBF application, or LTC2366ITS8#TRMPBF equivalent, this page provides verified technical context, validated pin functions, confirmed operating temperature range (–40°C to +85°C), real-world application cards, and two rigorously cross-checked alternative parts with documented functional differences.
Technical Context
The LTC2366ITS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting true 3Msps throughput via a 48MHz SCK clock. Its TS8 package enables independent VREF (1.4V to VDD) and OVDD (1V to VDD) supplies, allowing 0V–VREF analog input scaling and 1.8V/2.5V/3V-compatible digital interfacing without level shifters.
It features no data latency, sleep mode with 0.1µA typical current, and guaranteed operation across –40°C to +85°C. AC performance remains stable up to 1.5MHz input (Nyquist), with full-linear bandwidth of 2.5MHz (SINAD ≥ 68dB) and full-power bandwidth of 50MHz (0.1dB point).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - ensures monotonic transfer function and deterministic code mapping for precision measurement. |
| Sampling Rate | 3Msps maximum - supports undersampling of RF/IF signals up to 50MHz and real-time capture of fast transients. |
| SINAD | 72dB at fIN = 994kHz, fSMPL = 3Msps - enables >11.7 effective bits for high-fidelity signal digitization. |
| THD | –80.3dB at fIN = 994kHz - minimizes harmonic contamination in spectral analysis and communication receiver front-ends. |
| Supply Current | 2.6mA at 3Msps, 0.1µA in sleep mode - reduces average power in duty-cycled systems like portable medical monitors. |
| Analog Input Range | 0V to VREF, VREF = 1.4V to VDD - permits direct connection to low-voltage sensors (e.g., 1.8V-output MEMS accelerometers) without gain stages. |
| Digital Output Supply | OVDD = 1V to VDD - allows native interfacing with 1.8V FPGA I/O banks or 2.5V microcontroller peripherals. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (3.0mm × 1.7mm × 0.8mm), RoHS-compliant, lead-free finish, rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive analog supply | 2.35V–3.6V main supply; powers internal analog circuitry and defines upper limit for OVDD. |
| VREF (Pin 2) | External reference input | 1.4V–VDD reference voltage; sets full-scale analog input range (0V to VREF) and enables reduced-span operation. |
| GND (Pin 3) | Analog ground | Primary return path for analog signals and internal bias currents; must connect directly to solid ground plane. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; accepts 0V–VREF range with 20pF input capacitance during conversion. |
| OVDD (Pin 5) | Digital output supply | 1V–VDD supply for SDO driver; sets logic-high level and enables interoperability with mixed-voltage digital systems. |
| SDO (Pin 6) | Serial data output | Three-state SPI/MICROWIRE-compatible output; shifts 16-bit frame (2 leading zeros + 12-bit result + 2 trailing zeros) MSB-first on SCK falling edge. |
| SCK (Pin 7) | Serial clock input | Accepts up to 48MHz clock; falling edge clocks data out and controls conversion timing; tSCK min = 20.8ns. |
| CS (Pin 8) | Chip select input | Active-low signal that initiates conversion on falling edge and frames serial data transfer; t1 min = 4ns pulse width. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after final SCK edge - eliminates pipeline delay in closed-loop control systems. |
| Sleep mode (0.1µA) | Ultra-low quiescent current enables microamp-level system sleep states - critical for multi-year battery life in IoT endpoints. |
| Flexible reference interface | VREF pin supports externally sourced or internally derived references down to 1.4V - simplifies design of low-voltage sensor signal chains. |
| Independent OVDD supply | Decouples digital output swing from analog supply - avoids noise coupling and enables direct connection to 1.8V logic without translators. |
| Guaranteed –40°C to +85°C operation | Specified performance over industrial temperature range - suitable for automotive cabin electronics and outdoor industrial sensors. |

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 |
|---|---|---|---|
| ADS7953IRHBT | 12-bit, 1MSPS, SPI interface, 2.7–5.25V supply, no separate OVDD/VREF pins - uses internal reference or external VREF tied to VDD. | Requires external level-shifting for sub-2.7V digital interfaces; lacks independent OVDD for 1.8V logic compatibility. | Select when system uses 3.3V-only digital domain and higher supply voltage tolerance is acceptable. |
| MAX11198ETE+ | 12-bit, 3MSPS, SPI interface, 2.7–3.6V supply, integrated reference, no OVDD pin - digital outputs swing to VDD only. | Fixed 3.0V reference limits input span flexibility; no OVDD means incompatible with 1.8V I/O without translators. | Select when board space is constrained and reference integration outweighs need for scalable input range or mixed-voltage I/O. |
Compared with ADS7953IRHBT and MAX11198ETE+, the LTC2366ITS8#TRMPBF uniquely combines 3Msps sampling, independent VREF (1.4V–VDD) and OVDD (1V–VDD) supplies, and guaranteed –40°C to +85°C operation - making it the only option among the three that supports direct 1.8V digital interfacing and sub-2V sensor inputs without additional components.

FAQ
What is the maximum sampling rate supported by the LTC2366ITS8#TRMPBF?
The LTC2366ITS8#TRMPBF supports a maximum sampling rate of 3Msps, achieved using a 48MHz SCK clock with 14 SCK cycles per conversion. This is confirmed in the Absolute Maximum Ratings and Timing Characteristics tables of the official datasheet, where fSMPL(MAX) = 3MHz is specified for the LTC2366 variant under full industrial temperature range conditions.
Does the LTC2366ITS8#TRMPBF require an external reference voltage?
Yes, the LTC2366ITS8#TRMPBF requires an external reference voltage applied to the VREF pin (Pin 2). The VREF range is 1.4V to VDD, and the analog input range is 0V to VREF. Unlike some variants, it does not include an internal reference - this is explicitly stated in the Pin Functions section and confirmed by the TS8 package configuration in the datasheet.
What is the operating temperature range for the LTC2366ITS8#TRMPBF?
The LTC2366ITS8#TRMPBF is rated for operation from –40°C to +85°C, as indicated by the "I" grade suffix in its part number and confirmed in the Order Information table and Absolute Maximum Ratings section of the datasheet. This industrial temperature range is guaranteed for all electrical specifications unless otherwise noted.
Can the LTC2366ITS8#TRMPBF interface directly with a 1.8V microcontroller?
Yes, the LTC2366ITS8#TRMPBF can interface directly with a 1.8V microcontroller via its OVDD pin (Pin 5), which accepts 1V to VDD. By supplying 1.8V to OVDD, the SDO output swing is referenced to 1.8V, ensuring compatible logic levels without external level shifters - a key feature highlighted in the Applications Information section.
What is the sleep mode current consumption of the LTC2366ITS8#TRMPBF?
The LTC2366ITS8#TRMPBF draws 0.1µA typical supply current in sleep mode, as specified in the Power Requirement table under "Sleep Mode" for the –40°C to +85°C temperature range. This ultra-low quiescent current is enabled via the serial interface and is critical for extending battery life in intermittent-sampling applications.
