Analog Devices Inc. LTC2366HS6#TRMPBF

Overview

LTC2366HS6#TRMPBF 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 current draw. It delivers 72dB SINAD, –80.3dB THD at 994kHz input, and 73dB SNR, enabling high-fidelity signal digitization in space-constrained, battery-powered systems such as handheld medical sensors and automotive data loggers.

For engineers reviewing the LTC2366HS6#TRMPBF datasheet, LTC2366HS6#TRMPBF pinout, LTC2366HS6#TRMPBF application, or LTC2366HS6#TRMPBF equivalent, key selection criteria include its –40°C to 125°C extended temperature rating, no-data-latency operation, sleep mode consuming only 0.1µA, single-ended 0V–VDD analog input range, and SPI/MICROWIRE-compatible serial interface with MSB-first 16-bit frame (2 leading zeros + 12 data bits + 2 trailing zeros).

Technical Context

The LTC2366HS6#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, achieving full-scale input tracking without external components. Its aperture jitter of 0.3ns and acquisition time of 56ns support accurate undersampling of signals beyond Nyquist (up to 1.5MHz at 3Msps), while the internal reference derived from VDD eliminates need for external voltage references.

It uses a 3-wire serial interface (CS, SCK, SDO) with CS falling edge initiating conversion and framing data transfer; SDO transitions on SCK falling edges, outputting a fixed 16-bit frame regardless of clock speed. The device supports flexible timing - data valid after 15th SCK falling edge, with throughput time guaranteed at 333ns for 3Msps operation.

FAQ

What is the maximum sampling frequency supported by the LTC2366HS6#TRMPBF?

The LTC2366HS6#TRMPBF supports a maximum sampling frequency of 3Msps, achieved using a 48MHz SCK clock with guaranteed throughput time of 333ns. This specification applies across its full operating temperature range of –40°C to 125°C, and is validated by characterization per the datasheet timing table.

Does the LTC2366HS6#TRMPBF require an external voltage reference?

No, the LTC2366HS6#TRMPBF does not require an external voltage reference. In the S6 package variant, it uses VDD as the internal reference source, establishing a 0V to VDD analog input range. This eliminates external reference components and simplifies layout, especially in space-constrained applications.

How does the sleep mode function on the LTC2366HS6#TRMPBF?

The LTC2366HS6#TRMPBF enters sleep mode when CS remains high and SCK is held static (0V or VDD), reducing supply current to 0.1µA typical. Wake-up occurs on the next CS falling edge, with power-up time specified at 333ns. This feature enables aggressive power cycling in battery-operated systems without sacrificing responsiveness.

What is the analog input structure of the LTC2366HS6#TRMPBF?

The LTC2366HS6#TRMPBF features a single-ended analog input (AIN) referenced to GND, with input voltage range of 0V to VDD (2.35V–3.6V). It exhibits ±1µA input leakage and 4pF input capacitance during conversion, supporting direct connection to passive sensors and transducers without signal conditioning.

Is the LTC2366HS6#TRMPBF pin-compatible with other members of the LTC236x family?

The LTC2366HS6#TRMPBF shares the same 6-lead TSOT-23 (S6) pinout with the LTC2365HS6#TRMPBF and LTC2362HS6#TRMPBF, but differs in sampling rate and AC performance. While pinout is identical, substitution requires validation of timing, noise, and dynamic specifications for the target application due to inherent performance trade-offs between variants.
