Product details
Overview
LTC2366HTS8#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 –80dB THD at 3Msps, and supports external reference input (1.4V to VDD) and independent digital output supply (1V to VDD). It is used in high-speed, low-power data acquisition systems requiring precision sampling up to 125°C.
For engineers reviewing the LTC2366HTS8#TRMPBF datasheet, LTC2366HTS8#TRMPBF pinout, LTC2366HTS8#TRMPBF application, or LTC2366HTS8#TRMPBF equivalent, key selection criteria include guaranteed operation from –40°C to 125°C, no data latency, sleep mode with 0.1µA typical current, SPI/MICROWIRE-compatible serial interface, and support for reduced input spans down to 1.4V full-scale.
Technical Context
The LTC2366HTS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, enabling true 3Msps throughput without pipeline delay. Its timing-critical conversion cycle requires exactly 14 SCK falling edges for completion (tTHROUGHPUT = 333ns), with data output framed by CS and synchronized to SCK falling edges.
It features dual-supply flexibility: VREF sets analog input range (0V to VREF), while OVDD independently controls SDO output voltage swing (1V to VDD), allowing interoperability with mixed-voltage digital systems. The device maintains specified AC performance across its full industrial temperature range without derating.

Pinout & Package
Package: 8-lead plastic TSOT-23, 2.9mm × 1.6mm × 0.8mm, exposed pad optional, RoHS-compliant, tape-and-reel (500 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive analog supply | 2.35V–3.6V main supply; powers internal analog circuitry and defines maximum VREF. |
| VREF (Pin 2) | External reference input | Accepts 1.4V–VDD reference; sets full-scale analog input range (0V to VREF). |
| GND (Pin 3) | Analog ground | Primary return path for analog signals; must connect directly to solid ground plane. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; supports 0V to VREF range with 20pF input capacitance. |
| OVDD (Pin 5) | Digital output supply | 1V–VDD supply for SDO driver; enables level-shifting to 1.8V/2.5V/3V logic families. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first output; delivers two leading zeros + 12-bit result + two trailing zeros. |
| SCK (Pin 7) | Serial clock input | Accepts up to 48MHz clock; falling edge clocks out data and advances conversion state. |
| CS (Pin 8) | Chip select input | Active-low signal; falling edge initiates conversion and enables SDO; rising edge terminates transfer. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion completes within one sample period (333ns), enabling deterministic real-time control loops. |

FAQ
What is the maximum sampling rate supported by the LTC2366HTS8#TRMPBF?
The LTC2366HTS8#TRMPBF supports a maximum sampling rate of 3Msps, achieved with a 48MHz SCK clock and 14 SCK falling edges per conversion cycle. This rate is fully specified and guaranteed over the –40°C to 125°C operating temperature range, with tTHROUGHPUT = 333ns and no data latency.
Does the LTC2366HTS8#TRMPBF require an external reference voltage?
Yes, the LTC2366HTS8#TRMPBF requires an external reference voltage applied to the VREF pin (Pin 2). The reference range is 1.4V to VDD, and the analog input range is 0V to VREF. No internal reference is provided - this design enables flexible full-scale scaling and direct sensor interfacing without gain stages.
How does the OVDD pin on the LTC2366HTS8#TRMPBF improve system integration?
The OVDD pin (Pin 5) on the LTC2366HTS8#TRMPBF supplies the SDO output driver independently of VDD, allowing the digital output swing to be set between 1V and VDD. This enables direct interfacing with 1.8V, 2.5V, or 3V logic families without external level shifters - simplifying PCB layout and reducing BOM count in mixed-voltage systems.
What is the sleep mode current consumption of the LTC2366HTS8#TRMPBF?
The LTC2366HTS8#TRMPBF draws 0.1µA typical supply current in sleep mode, with CS = VDD and SCK = 0V or VDD. This ultra-low quiescent current is specified over the full –40°C to 125°C temperature range and enables multi-year battery life in duty-cycled sensing applications.
Is the LTC2366HTS8#TRMPBF pin-compatible with other members of the LTC2365/LTC2366 family?
Yes, the LTC2366HTS8#TRMPBF shares identical pinout and footprint with all TS8-package variants in the LTC2365/LTC2366 family, including LTC2365HTS8#TRMPBF and LTC2366CTS8#TRMPBF. All use the same 8-lead TSOT-23 package with VDD/VREF/GND/AIN/OVDD/SDO/SCK/CS pin assignment and compatible timing and interface behavior.
