Product details
Overview
LTC2366HS6#TRPBF from Analog Devices (formerly Linear Technology) is a 3Msps, 12-bit successive-approximation ADC in a 6-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 2.6mA typical supply current, 72dB SINAD at 3Msps, and –40°C to 125°C extended temperature range. It features no data latency, sleep mode (0.1µA), and direct sensor interface capability via high-impedance single-ended analog input (0V to VDD).
For engineers reviewing the LTC2366HS6#TRPBF datasheet, LTC2366HS6#TRPBF pinout, LTC2366HS6#TRPBF application, or LTC2366HS6#TRPBF equivalent, this page delivers verified specifications, thermal-grade packaging context, serial interface timing constraints, and real-world use cases for high-speed, low-power embedded data acquisition.
Technical Context
The LTC2366HS6#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting up to 48MHz SCK for full 3Msps throughput. Its analog input is referenced directly to VDD (0V to VDD), eliminating external reference components and simplifying layout in space-constrained systems.
It uses a 3-wire SPI/MICROWIRE-compatible serial interface with MSB-first 16-cycle frame (two leading zeros + 12 data bits + two trailing zeros), where CS falling edge initiates conversion and SDO transitions on SCK falling edges. Sleep mode is entered via CS high/idle state and exits in ≤333ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sampling Rate | 3Msps maximum - enables real-time digitization of signals up to 1.5MHz Nyquist bandwidth without undersampling penalties. |
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and deterministic code mapping across full temperature range. |
| SINAD | 72dB at 3Msps, fIN = 994kHz - supports >11.6 ENOB for precision measurement in noisy industrial environments. |
| Supply Current | 2.6mA typical at 3Msps - achieves 6mW power dissipation at 3V, enabling battery operation in portable instrumentation. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC analog input modules. |
| Input Range | 0V to VDD (single-ended) - allows direct connection to unbuffered sensors or transducers without level-shifting circuitry. |
| Sleep Current | 0.1µA typical - reduces system standby power by >99% during idle intervals in duty-cycled sensing applications. |
Pinout & Package
Package: 6-lead Plastic TSOT-23, 1.6mm × 1.6mm × 0.55mm profile, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply input | 2.35V–3.6V analog/digital core supply; also defines full-scale input range (0V to VDD); requires 10µF ceramic bypass to GND. |
| GND (Pin 2) | Analog and digital ground | Single-point connection to solid ground plane; critical for noise immunity and DC accuracy stability. |
| AIN (Pin 3) | Analog input | High-impedance (20pF), single-ended input referenced to GND; accepts 0V to VDD range without external gain/attenuation. |
| SCK (Pin 4) | Serial clock input | Accepts up to 48MHz clock; falling edge clocks out data and advances conversion state machine. |
| SDO (Pin 5) | Three-state serial data output | MSB-first 16-bit frame (00 + 12-bit result + 00); driven only when CS is low; swing matches VDD voltage. |
| CS (Pin 6) | Chip select input | Active-low signal initiating conversion on falling edge; frames serial data transfer and controls SDO enable/disable timing. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after final SCK edge - eliminates pipeline delay in closed-loop control systems. |
| Integrated sample-and-hold | Aperture jitter <0.3ns - preserves signal integrity for high-frequency inputs up to 50MHz full-power bandwidth. |
| Flexible serial interface | 14- or 16-cycle framing compatible with standard SPI peripherals - avoids custom logic or FPGA glue logic in MCU-based designs. |
| Reduced span operation | Valid down to 1.4V full scale - maintains 342µV LSB resolution even with lower VDD, enabling ultra-low-voltage sensor interfacing. |
| Extended temperature grade | H-grade qualification (–40°C to +125°C) - ensures parametric compliance in harsh thermal environments without derating. |

FAQ
What is the maximum sampling rate supported by the LTC2366HS6#TRPBF?
The LTC2366HS6#TRPBF supports a maximum sampling rate of 3Msps, achieved using a 48MHz SCK clock with 14 SCK cycles per conversion. This rate is guaranteed over the full –40°C to +125°C operating temperature range and enables digitization of signals up to 1.5MHz Nyquist bandwidth while maintaining 72dB SINAD performance.
Does the LTC2366HS6#TRPBF require an external reference voltage?
No, the LTC2366HS6#TRPBF does not require an external reference. In the S6 package variant, the analog input full-scale range is defined by VDD (0V to VDD), eliminating the need for a dedicated reference IC or resistor divider. This simplifies design, reduces component count, and improves layout robustness in space-constrained applications.
What is the sleep mode current consumption of the LTC2366HS6#TRPBF?
The LTC2366HS6#TRPBF draws 0.1µA typical supply current in sleep mode, verified over the –40°C to +125°C temperature range. This ultra-low quiescent current is activated automatically when CS remains high and SCK is inactive, making the LTC2366HS6#TRPBF ideal for battery-operated devices with intermittent sampling requirements.
Can the LTC2366HS6#TRPBF interface directly with a 1.8V microcontroller?
No-the LTC2366HS6#TRPBF S6 package drives SDO with VDD-referenced logic levels (VIH ≥ 2.35V for VDD > 2.7V), so it cannot directly interface with 1.8V I/O without level translation. For native 1.8V compatibility, the TS8-package variants (e.g., LTC2366HTS8#TRPBF) provide separate OVDD pin to set SDO output swing independently of VDD.
What package type and dimensions does the LTC2366HS6#TRPBF use?
The LTC2366HS6#TRPBF uses a 6-lead Plastic TSOT-23 package measuring 1.6mm × 1.6mm × 0.55mm with 0.65mm lead pitch. It features a non-electrical exposed pad and is rated for –40°C to +125°C operation. This ultra-compact footprint enables placement adjacent to sensors in dense PCB layouts without thermal or routing compromises.
