Analog Devices Inc. LTC2360CTS8#TRMPBF

Overview

LTC2360CTS8#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 and 73dB SNR. It features a dedicated external reference input (VREF), independent digital output supply (OVDD), SPI/MICROWIRE-compatible serial interface, and sleep mode drawing 0.1μA - enabling high-precision data acquisition in battery-powered sensor interfaces.

For engineers reviewing the LTC2360CTS8#TRMPBF datasheet, LTC2360CTS8#TRMPBF pinout, LTC2360CTS8#TRMPBF application, or LTC2360CTS8#TRMPBF equivalent, key selection considerations include its 100ksps throughput, 0V–VREF analog input range (1.4V to VDD), 12-bit no-missing-codes performance, TSOT-23-8 thermal characteristics (θJA = 250°C/W), and guaranteed operation from 0°C to 70°C.

Technical Context

The LTC2360CTS8#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to fix conversion timing at 10μs (tTHROUGHPUT). Its analog front-end accepts single-ended inputs referenced to GND, with full-scale range set by VREF (1.4V–VDD), and supports reduced spans down to 1.4V for direct transducer interfacing without gain stages.

Digital communication uses a 3-wire SPI-compatible interface: CONV initiates conversion on rising edge and enables SDO on falling edge; SCK clocks data (MSB-first) on falling edges; SDO outputs 12-bit result followed by trailing zeros. OVDD (1V–VDD) independently sets digital output swing, enabling interoperability with 1.8V/2.5V/3V logic domains.

FAQ

What is the maximum sampling rate supported by the LTC2360CTS8#TRMPBF?

The LTC2360CTS8#TRMPBF supports a maximum sampling rate of 100ksps, corresponding to a minimum throughput time of 10μs. This rate is fixed by the internal oscillator and applies across the full 0°C to 70°C operating temperature range. At lower rates, supply current scales down due to automatic sleep-mode entry after each conversion, reducing average power consumption proportionally.

Does the LTC2360CTS8#TRMPBF require an external reference voltage?

Yes, the LTC2360CTS8#TRMPBF requires an external reference voltage applied to the VREF pin, which sets the full-scale analog input range (0V to VREF). The VREF range is specified as 1.4V to VDD, allowing use with precision references such as 2.048V or 2.5V. Unlike some variants, the LTC2360CTS8#TRMPBF does not include an internal reference and relies entirely on this external connection for accuracy and ratiometric operation.

Can the LTC2360CTS8#TRMPBF interface directly with a 1.8V microcontroller?

Yes, the LTC2360CTS8#TRMPBF can interface directly with a 1.8V microcontroller by setting OVDD = 1.8V. The OVDD pin (Pin 5) independently powers the SDO output driver, allowing logic-level compatibility with 1.8V, 2.5V, or 3V digital systems without external level shifters. VDD and VREF remain at their required analog supply levels (e.g., 3.0V), preserving analog performance while enabling seamless digital integration.

What is the purpose of the CONV pin on the LTC2360CTS8#TRMPBF?

The CONV pin on the LTC2360CTS8#TRMPBF serves two critical functions: a rising edge initiates conversion and places SDO in high-impedance state, while a falling edge enables SDO output and synchronizes serial data transfer. After conversion completes, the device automatically enters sleep mode if CONV remains high, reducing supply current to 0.1μA. This dual-role pin provides precise timing control and enables ultra-low-power duty-cycled operation.

Is the LTC2360CTS8#TRMPBF pin-compatible with other members of the LTC236x family?

Yes, the LTC2360CTS8#TRMPBF is pin-compatible with the LTC2361CTS8#TRMPBF and LTC2362CTS8#TRMPBF in the TS8 package - all share identical 8-pin TSOT-23 pinout, VREF/OVDD functionality, and serial interface timing. This allows drop-in replacement for higher-speed variants (250ksps/500ksps) without PCB changes, provided system timing and power delivery meet the respective specifications.
