Analog Devices Inc. LTC2360ITS8#TRMPBF

Overview

LTC2360ITS8#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 SPI/MICROWIRE-compatible serial I/O, 0V to VREF analog input range, and supports external reference (1.4V to VDD) and independent digital output supply (1V to VDD). It is used in battery-powered data acquisition front-ends where low power, small size, and direct sensor interfacing are critical.

For engineers reviewing the LTC2360ITS8#TRMPBF datasheet, LTC2360ITS8#TRMPBF pinout, LTC2360ITS8#TRMPBF application, or LTC2360ITS8#TRMPBF equivalent, key selection considerations include its guaranteed –40°C to +85°C industrial temperature range, 73dB SNR at 49kHz input, no data latency, dedicated VREF and OVDD pins for flexible system-level voltage domain isolation, and TSOT-23-8 package compatibility with high-density PCB layouts.

Technical Context

The LTC2360ITS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, controlled by an internal oscillator enabling fixed 100ksps throughput without external clock dependency. Its timing is defined by CONV-triggered conversion start and SCK-synchronized serial readout, with acquisition time of 2μs and conversion time of 8μs.

It supports two distinct analog input configurations: full-scale range tied to VREF (TS8 package), allowing reduced spans down to 1.4V for improved resolution on low-voltage sensors, and independent OVDD control (1V to VDD) enabling interoperability with 1.8V/2.5V/3V logic families without level shifters.

FAQ

What is the maximum sampling rate supported by the LTC2360ITS8#TRMPBF?

The LTC2360ITS8#TRMPBF supports a maximum sampling rate of 100ksps, as specified in its datasheet and confirmed by timing parameters including t_THROUGHPUT = 10μs and f_SMPL(MAX) = 100kHz. This rate is fixed by the internal oscillator and does not require an external clock source. At this rate, the device draws 0.5mA from VDD and achieves 73dB SNR with a 49kHz input sine wave.

Does the LTC2360ITS8#TRMPBF require an external reference voltage?

Yes, the LTC2360ITS8#TRMPBF requires an external reference voltage applied to the VREF pin (Pin 2) in its TSOT-23-8 package configuration. The reference range is 1.4V to VDD, and it directly defines the full-scale analog input range (0V to VREF). Unlike the 6-lead S6 variant, the TS8 package does not use VDD as the default reference - VREF must be supplied and bypassed with a 2.2μF capacitor.

Can the LTC2360ITS8#TRMPBF interface directly with a 1.8V microcontroller?

Yes, the LTC2360ITS8#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 referenced to that voltage, producing logic-high levels near 1.8V and logic-low levels near 0V - fully compatible with 1.8V I/O standards without level-shifting circuitry. VDD and VREF remain independent and may operate at higher voltages (e.g., 3.3V).

What is the guaranteed operating temperature range for the LTC2360ITS8#TRMPBF?

The LTC2360ITS8#TRMPBF is rated for operation from –40°C to +85°C, denoted by the "I" grade in its part number suffix. All key specifications - including integral linearity (±0.25LSB typ), SNR (73dB), supply current (0.5mA at 100ksps), and timing parameters - are guaranteed across this full industrial temperature range, making it suitable for automotive and harsh-environment applications.

How does the LTC2360ITS8#TRMPBF achieve ultra-low power consumption?

The LTC2360ITS8#TRMPBF achieves ultra-low power through automatic sleep mode activation after each conversion when CONV remains high, reducing supply current to 0.1μA typical. Its 0.5mA operational current at 100ksps scales linearly with sample rate, and the absence of external clocking or biasing components minimizes system-level power overhead - enabling multi-year battery life in duty-cycled sensor nodes.
