Analog Devices Inc. LTC2360ITS8#TRPBF

Overview

LTC2360ITS8#TRPBF 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 active current and 0.1μA sleep current. It features a high-impedance single-ended analog input (0V to VREF), SPI/MICROWIRE-compatible serial interface, and supports external reference (1.4V to VDD) for flexible full-scale scaling - used in battery-powered data acquisition and portable sensor interfaces.

For engineers reviewing the LTC2360ITS8#TRPBF datasheet, LTC2360ITS8#TRPBF pinout, LTC2360ITS8#TRPBF application, or LTC2360ITS8#TRPBF equivalent, key selection considerations include its guaranteed –40°C to +85°C industrial temperature range, 73dB SNR at 49kHz input, no data latency, dedicated OVDD output supply (1V to VDD), and TSOT-23-8 pin compatibility across the LTC236x family.

Technical Context

The LTC2360ITS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to enforce precise 100ksps sampling without external clock dependency. Its conversion timing is deterministic: 2μs acquisition + 8μs conversion = 10μs total throughput time, with SDO data valid 16ns after CONV↓ and stable on SCK↓ falling edge.

It operates in two distinct power states: active mode during conversion (0.5mA at 100ksps), then automatic entry into ultra-low-power sleep mode (0.1μA) when CONV remains high post-conversion. The TSOT-23-8 package provides separate VREF and OVDD pins, enabling independent analog reference scaling and digital I/O voltage control - critical for interfacing with mixed-voltage systems (e.g., 3.3V analog domain, 1.8V FPGA logic).

FAQ

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

The LTC2360ITS8#TRPBF supports a maximum sampling rate of 100ksps, with guaranteed timing parameters including 2μs acquisition time and 8μs conversion time. This rate is fixed by the internal oscillator and does not require an external clock source. At this rate, the device draws 0.5mA typical supply current from a 3V supply and delivers 73dB SNR at 49kHz input frequency.

Does the LTC2360ITS8#TRPBF require an external reference voltage?

Yes - the LTC2360ITS8#TRPBF (TSOT-23-8 package) requires an external reference voltage applied to the VREF pin, which sets the full-scale analog input range (0V to VREF). VREF must be between 1.4V and VDD. Unlike the 6-lead S6 variant, the TS8 version does not use VDD as the reference, enabling flexible scaling and improved accuracy with precision external references.

How does the sleep mode function in the LTC2360ITS8#TRPBF?

The LTC2360ITS8#TRPBF automatically enters sleep mode after each conversion when the CONV pin remains high, reducing supply current to 0.1μA typical. In sleep mode, bias currents are shut down and only leakage paths remain active. The device exits sleep mode on the falling edge of CONV, completing acquisition in t_ACQ = 2μs before conversion begins - enabling precise burst-mode operation with minimal average power.

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

Yes - the LTC2360ITS8#TRPBF supports direct 1.8V logic interfacing via its dedicated OVDD pin (Pin 5), which powers the SDO output driver. When OVDD = 1.8V, SDO swings between 0V and 1.8V, meeting VIH/VIL thresholds of standard 1.8V CMOS inputs. This eliminates the need for external level-shifting circuitry while maintaining full 12-bit accuracy and timing integrity.

What is the analog input impedance and capacitance of the LTC2360ITS8#TRPBF?

The LTC2360ITS8#TRPBF features a high-impedance analog input with 20pF capacitance between conversions and 4pF during conversion. Input leakage current is ±1μA maximum over temperature. This allows direct connection to high-output-impedance sensors (e.g., thermistors, piezoelectric elements) without buffering, provided source impedance is ≤1kΩ for optimal settling within the 2μs acquisition window.
