Product details
Overview
LTC2366CTS8#TRPBF from Analog Devices (formerly Linear Technology) is a 3Msps, 12-bit successive-approximation analog-to-digital converter (SAR ADC) with single-ended analog input, dedicated external reference (VREF), and independent digital output supply (OVDD). It operates from a 2.35V–3.6V VDD supply, draws 2.6mA at full speed, delivers 72dB SINAD and –80dB THD at 3Msps, and supports 1V–3.6V OVDD for interfacing with mixed-voltage digital systems - ideal for compact, battery-powered data acquisition in medical imaging and handheld terminals.
For engineers reviewing the LTC2366CTS8#TRPBF datasheet, LTC2366CTS8#TRPBF pinout, LTC2366CTS8#TRPBF application, or LTC2366CTS8#TRPBF equivalent, this page provides verified technical context, TSOT-23-8 pin mapping, real-world use scenarios, and validated alternative options - all grounded in the official LTC2365/LTC2366 datasheet (23656fb) and Linear/Analog Devices product documentation.
Technical Context
The LTC2366CTS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting true 3Msps throughput via a 48MHz SCK clock. Its TSOT-23-8 package separates analog reference (VREF, 1.4V–VDD) and digital output supply (OVDD, 1V–VDD), enabling precise full-scale spans down to 1.4V and flexible interface to 1.8V/2.5V/3V logic without level shifters.
It features no data latency, 0.1µA sleep mode current, SPI/MICROWIRE-compatible 3-wire serial interface (CS/SCK/SDO), and guaranteed operation from 0°C to 70°C (C-grade). The 12-bit conversion result is serialized as two leading zeros + 12 data bits + two trailing zeros, MSB-first, with SDO output swing controlled solely by OVDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sampling Rate | 3Msps - enables real-time digitization of signals up to 1.5MHz Nyquist bandwidth with minimal aliasing. |
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and deterministic code transitions. |
| SINAD | 72dB at fIN = 994kHz, fSMPL = 3Msps - supports >11.6 ENOB for high-fidelity signal capture. |
| Supply Current | 2.6mA typical at 3Msps - achieves 6mW power dissipation at 3V, critical for thermally constrained designs. |
| Analog Input Range | 0V to VREF (1.4V–3.6V) - allows direct sensor connection without gain stages when VREF ≥ 1.4V. |
| Digital Output Supply | OVDD = 1V to VDD - permits native interfacing with 1.8V FPGA I/O banks or 2.5V microcontroller peripherals. |
| Integral Linearity | ±0.25 LSB typical - ensures <0.006% full-scale error for precision measurement applications. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (0°C to 70°C operating range), 2.9mm × 1.6mm footprint, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog supply input | 2.35V–3.6V main supply; defines internal bias and analog core operation; requires 10µF bypass to GND. |
| VREF (Pin 2) | External reference input | 1.4V–VDD reference voltage; sets full-scale analog input range (0V to VREF); requires 4.7µF bypass. |
| GND (Pin 3) | Analog ground | Common return for analog circuitry; must connect directly to solid ground plane to minimize noise coupling. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; accepts 0V to VREF; high-impedance (±1µA leakage) with 4pF capacitance. |
| OVDD (Pin 5) | Digital output supply | 1V–VDD supply for SDO driver; determines logic-high level and drive strength; requires 4.7µF bypass. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first output; transmits two leading zeros + 12-bit result + two trailing zeros; swing set by OVDD. |
| SCK (Pin 7) | Serial clock input | Edge-triggered clock (max 48MHz); falling edge clocks out data; timing-critical for 3Msps throughput. |
| CS (Pin 8) | Chip select input | Active-low control; falling edge initiates conversion and enables SDO; rising edge returns SDO to Hi-Z. |
Key Features
| Feature | Design Value |
|---|---|
| 3Msps sampling with 48MHz SCK | Enables undersampling of RF and IF signals up to 1.5MHz while maintaining 72dB SINAD - reduces front-end filtering complexity. |
| Independent OVDD pin | Decouples digital I/O voltage from analog supply, allowing seamless integration with low-voltage FPGAs and SoCs without external level translators. |
| 1.4V minimum VREF | Supports high-resolution digitization of low-output sensors (e.g., 1.5V-output thermocouple amps) without amplification, reducing component count and noise. |
| No data latency | Conversion result is available immediately after final SCK edge - eliminates pipeline delay in closed-loop control systems. |
| 0.1µA sleep mode current | Reduces system standby power by >99% versus active mode, extending battery life in portable instrumentation and IoT endpoints. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7886IDBVR | 12-bit, 3Msps, but uses internal reference only (no VREF pin); OVDD not supported; 6-pin SOT-23 package. | Lacks external reference flexibility and mixed-voltage I/O - unsuitable where VREF < VDD or OVDD ≠ VDD is required. | Select only if fixed 2.5V internal reference suffices and board space constraints favor 6-pin footprint. |

FAQ
What is the maximum sampling rate supported by the LTC2366CTS8#TRPBF?
The LTC2366CTS8#TRPBF supports a maximum sampling rate of 3Msps, achieved using a 48MHz SCK clock with a minimum throughput time of 333ns. This rate is fully characterized and guaranteed over the 0°C to 70°C operating temperature range specified for the C-grade variant.
Does the LTC2366CTS8#TRPBF require an external reference voltage?
Yes, the LTC2366CTS8#TRPBF requires an external reference voltage applied to the VREF pin (Pin 2). VREF sets the full-scale analog input range (0V to VREF) and must be between 1.4V and VDD (2.35V–3.6V). Unlike the S6-package variants, the TS8 package does not use VDD as the reference.
Can the LTC2366CTS8#TRPBF interface with a 1.8V microcontroller?
Yes, the LTC2366CTS8#TRPBF can interface directly with a 1.8V microcontroller by setting OVDD (Pin 5) to 1.8V. This configures the SDO output swing to match the microcontroller's logic-high threshold, eliminating the need for external level-shifting circuitry.
What is the sleep mode current consumption of the LTC2366CTS8#TRPBF?
The LTC2366CTS8#TRPBF draws a typical sleep mode current of 0.1µA when CS is held high and SCK is static. This ultra-low quiescent current significantly reduces system-level power during idle periods, extending battery life in portable instrumentation.
Is the LTC2366CTS8#TRPBF pin-compatible with the LTC2365CTS8#TRPBF?
Yes, the LTC2366CTS8#TRPBF and LTC2365CTS8#TRPBF share identical TSOT-23-8 pinouts and package dimensions. However, they differ in maximum sampling rate (3Msps vs. 1Msps), supply current (2.6mA vs. 2mA), and dynamic performance - so functional substitution requires validation of timing and AC specifications.
