Product details
Overview
LTC2366IS6#TRPBF from Analog Devices (formerly Linear Technology) is a 3Msps, 12-bit 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 2.6mA typical supply current. It features 72dB SINAD at 3Msps, 0V–VDD analog input range, no data latency, and –40°C to +85°C industrial temperature rating - ideal for compact, battery-powered sensor interfaces requiring high-speed, low-power digitization.
For engineers reviewing the LTC2366IS6#TRPBF datasheet, LTC2366IS6#TRPBF pinout, LTC2366IS6#TRPBF application, or LTC2366IS6#TRPBF equivalent, key selection considerations include its 3Msps sampling rate with 48MHz SCK support, 0.34LSB RMS transition noise, sleep mode (0.1µA), single-supply operation, and compatibility with SPI/MICROWIRE controllers in space-constrained embedded systems.
Technical Context
The LTC2366IS6#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, enabling true 12-bit resolution without missing codes across its full industrial temperature range. Its analog input is single-ended with respect to GND, referenced directly to VDD (0V to VDD), eliminating external reference components.
Serial communication uses a 3-wire SPI-compatible interface (CS, SCK, SDO) with MSB-first 16-bit frame format: two leading zeros, 12 data bits, two trailing zeros. Conversion is initiated on CS falling edge; SDO transitions on SCK falling edges, with data valid hold time of 5ns and no latency between conversion start and first output bit.
Key Specifications

|---|---|
| Sampling Rate | 3Msps maximum - enables real-time capture of signals up to 1.5MHz Nyquist bandwidth |
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function for precision measurement |
| SINAD | 72dB at 3Msps, fIN = 994kHz - supports >11.6 ENOB for high-fidelity signal reconstruction |
| Supply Current | 2.6mA typical at 3Msps - achieves 6mW power dissipation at 3V, critical for portable designs |
| Input Range | 0V to VDD (2.35V–3.6V) - allows direct connection to sensors without level-shifting or gain stages |
| Sleep Current | 0.1µA typical - reduces system standby power by >99% versus active mode |

Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1.6mm × 1.6mm footprint, 0.95mm height, thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply input | 2.35V–3.6V single supply; defines full-scale analog input range (0V to VDD); requires 10µF ceramic bypass to GND |
| GND (Pin 2) | Analog ground reference | Must connect directly to solid ground plane; serves as return for analog input and internal circuitry |
| AIN (Pin 3) | Analog input | Single-ended, high-impedance (20pF capacitance), 0V to VDD range; accepts direct sensor outputs |
| SCK (Pin 4) | Serial clock input | Accepts up to 48MHz clock; falling edge clocks out serial data; timing-critical for 3Msps throughput |
| SDO (Pin 5) | Three-state serial data output | MSB-first 16-bit frame (00 + 12-bit code + 00); output swing tied to VDD; Hi-Z when CS high |
| CS (Pin 6) | Chip select input | Active-low; falling edge initiates conversion and enables SDO; minimum pulse width 4ns |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | First output bit available immediately after CS fall - eliminates pipeline delay in closed-loop control |
| Integrated sample-and-hold | Aperture jitter <0.3ns - preserves signal integrity for high-frequency inputs up to 30MHz full-power bandwidth |
| SPI/MICROWIRE compatibility | Standard 3-wire interface with 16-bit frame - interoperable with common microcontrollers and FPGAs without protocol translation |
| Reduced power at low throughput | Dynamic current scaling via SCK frequency - IDD drops linearly below 3Msps, optimizing efficiency in burst-mode acquisition |
| Industrial temperature grade | –40°C to +85°C operation with guaranteed specs - avoids thermal recalibration in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7883IDBVR | 1Msps max, 12-bit, 2.7–5.5V supply, 1.5mA @ 1Msps, 6-pin SOT-23 | Lower speed and wider supply range; lacks sleep mode (1µA shutdown) | Choose for cost-sensitive, lower-throughput designs where 3Msps is unnecessary and 5V logic compatibility is required. |
| MAX11166ETT+ | 3Msps, 12-bit, 2.7–3.6V supply, 2.5mA @ 3Msps, 6-pin TDFN | Same speed/power but different package (TDFN vs TSOT-23); requires external reference for full-scale flexibility | Choose when board layout permits TDFN and system needs programmable reference voltage independent of VDD. |
Compared with ADS7883IDBVR and MAX11166ETT+, the LTC2366IS6#TRPBF delivers superior dynamic performance (72dB SINAD vs ≤70dB) and tighter integration (VDD-referenced input, no external ref needed), making it optimal for miniaturized, high-fidelity sensor nodes where board area and BOM count are constrained.

FAQ
What is the maximum sampling rate supported by the LTC2366IS6#TRPBF?
The LTC2366IS6#TRPBF supports a maximum sampling rate of 3Msps, achieved with a 48MHz SCK clock and 14 SCK cycles per conversion. This rate is fully characterized over the –40°C to +85°C temperature range and maintains 72dB SINAD at 994kHz input frequency. The device also operates reliably at lower rates (e.g., 1Msps or 500ksps) with proportional reductions in supply current.
Does the LTC2366IS6#TRPBF require an external reference voltage?
No, the LTC2366IS6#TRPBF does not require an external reference voltage. In the S6 package, it uses the VDD supply as the reference, establishing a 0V to VDD analog input range. This eliminates external reference components and simplifies design - unlike the TS8 variant (e.g., LTC2366ITS8#TRPBF), which provides a dedicated VREF pin for flexible scaling.
How does the sleep mode of the LTC2366IS6#TRPBF reduce system power consumption?
The LTC2366IS6#TRPBF enters sleep mode when CS remains high and SCK is held static, drawing only 0.1µA typical supply current. This reduces total system standby power by >99% compared to active operation (2.6mA). Wake-up is instantaneous - conversion begins within 333ns of CS assertion - making it ideal for duty-cycled sensor acquisition in battery-powered devices.
What is the analog input structure of the LTC2366IS6#TRPBF?
The LTC2366IS6#TRPBF features a single-ended, high-impedance analog input (AIN) referenced to GND, with a full-scale range of 0V to VDD (2.35V–3.6V). Input capacitance is 20pF between conversions and 4pF during sampling. It accepts direct connection to resistive sensors, thermistors, and transducer outputs without buffering, supporting reduced-span operation down to 1.4V full scale in TS8 variants (not applicable to S6).
Is the LTC2366IS6#TRPBF compatible with standard SPI interfaces?
Yes, the LTC2366IS6#TRPBF is SPI/MICROWIRE-compatible, using a 3-wire interface (CS, SCK, SDO) with MSB-first 16-bit frames (two leading zeros, 12 data bits, two trailing zeros). It requires no MISO/MOSI bidirectional handling - SDO is output-only. Timing adheres to standard setup/hold requirements (e.g., t4 = 15ns data valid after SCK↓), ensuring plug-and-play integration with most microcontrollers and FPGAs.
