Analog Devices Inc. LTC2360HTS8#TRMPBF

Overview

LTC2360HTS8#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 100ksps successive-approximation ADC in an 8-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 0.5mA typical supply current at full rate and 0.1μA sleep current. It features a dedicated external reference input (VREF), independent digital output supply (OVDD), SPI/MICROWIRE-compatible serial interface, and supports analog input spans down to 1.4V - enabling direct sensor interfacing in high-temperature industrial data acquisition systems.

For engineers reviewing the LTC2360HTS8#TRMPBF datasheet, LTC2360HTS8#TRMPBF pinout, LTC2360HTS8#TRMPBF application, or LTC2360HTS8#TRMPBF equivalent, key selection considerations include its –40°C to 125°C extended temperature rating, 73dB SNR at 49kHz, ±1 LSB integral linearity, no data latency, and TSOT-23-8 pin compatibility across the LTC236x family for drop-in thermal and layout reuse.

Technical Context

The LTC2360HTS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to guarantee fixed 10μs throughput time (tACQ + tCONV = 10μs). Its analog front-end accepts single-ended inputs referenced to GND with full-scale range 0V to VREF (1.4V–VDD), and supports reduced-span operation without gain stages.

Digital communication uses a 3-wire SPI-compatible interface: CONV initiates conversion on rising edge and enables SDO output on falling edge; SCK clocks out 12-bit MSB-first data on falling edges; SDO output swing is independently controlled by OVDD (1V–VDD), allowing interoperability with 1.8V/2.5V/3V logic domains while maintaining rail-to-rail analog performance.

FAQ

What is the maximum sampling rate supported by the LTC2360HTS8#TRMPBF?

The LTC2360HTS8#TRMPBF supports a maximum sampling rate of 100ksps, with guaranteed 10μs total throughput time (tACQ + tCONV) across its full –40°C to +125°C operating range. This rate is fixed by its internal oscillator and does not require external clock configuration - ensuring deterministic timing for real-time control loops.

Does the LTC2360HTS8#TRMPBF require an external reference voltage?

Yes, the LTC2360HTS8#TRMPBF requires an external reference voltage applied to the VREF pin (Pin 2). It supports reference voltages from 1.4V up to VDD (3.6V), enabling flexible full-scale range selection. The device does not include an internal reference, so precision external references (e.g., REF192, ADR3425) must be used for calibrated measurements.

Can the LTC2360HTS8#TRMPBF interface directly with a 1.8V microcontroller?

Yes, the LTC2360HTS8#TRMPBF can interface directly with a 1.8V microcontroller using its OVDD pin (Pin 5). By supplying OVDD = 1.8V, the SDO output swing is constrained to 0V–1.8V, matching the MCU's input logic thresholds without level-shifting circuitry - preserving signal integrity and reducing component count.

What is the sleep current specification for the LTC2360HTS8#TRMPBF?

The LTC2360HTS8#TRMPBF draws 0.1μA typical supply current in sleep mode when CONV remains high after conversion completion. This ultra-low quiescent current is guaranteed across the full –40°C to +125°C temperature range and enables multi-year battery life in intermittent-sampling applications such as remote condition monitoring sensors.

How does the LTC2360HTS8#TRMPBF handle analog input overvoltage conditions?

The LTC2360HTS8#TRMPBF includes internal clamping diodes on AIN and VREF pins. When these pins exceed VDD + 0.3V or fall below –0.3V, current is shunted to VDD or GND respectively. The device tolerates >100mA transient overcurrent without latch-up - protecting against sensor fault conditions in industrial field wiring environments.
