Product details
Overview
LTC2360CTS8#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 supply current and 73dB SNR. It features a dedicated external reference input (VREF), independent digital output supply (OVDD), and SPI/MICROWIRE-compatible serial interface - used in portable data acquisition, battery-powered sensor interfaces, and compact industrial monitoring systems.
For engineers reviewing the LTC2360CTS8#TRPBF datasheet, LTC2360CTS8#TRPBF pinout, LTC2360CTS8#TRPBF application, or LTC2360CTS8#TRPBF equivalent, key selection criteria include its 100ksps sampling rate, 0.5mA operational current at full speed, 1.4V–VDD reference range, 1V–VDD OVDD flexibility, and guaranteed operation from 0°C to 70°C in the TS8 package.
Technical Context
The LTC2360CTS8#TRPBF implements a switched-capacitor SAR architecture with internal sample-and-hold, controlled by an internal oscillator to deliver precise 100ksps throughput. Its analog input is single-ended (0V to VREF), referenced to GND, and supports reduced spans down to 1.4V full-scale for direct transducer interfacing without gain stages.
Serial communication uses a 3-wire interface (CONV, SCK, SDO) with MSB-first transmission synchronized on SCK falling edges; CONV rising edge initiates conversion, and CONV low enables SDO output. Sleep mode activates automatically after conversion when CONV remains high, reducing supply current to 0.1μA typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - ensures monotonic transfer function and unambiguous digital representation of analog inputs. |
| Sampling Rate | 100ksps maximum - defines real-time signal capture capability for baseband audio, sensor telemetry, and control loop sampling. |
| SNR | 73dB typical at fIN = 49kHz - enables >11.8 effective bits for precision measurement in noise-sensitive applications. |
| Supply Current | 0.5mA typical at 100ksps, 0.1μA in sleep - supports ultra-low-power operation in duty-cycled or event-triggered systems. |
| Reference Range | 1.4V to VDD (TS8 package) - allows flexible scaling for low-voltage sensors while maintaining 342μV LSB resolution at 1.4V full-scale. |
| Digital Output Supply | OVDD = 1V to VDD - permits interoperability with 1.8V, 2.5V, or 3V logic families without level-shifting circuitry. |
| Operating Temp | 0°C to 70°C - qualified for commercial-grade embedded instrumentation and consumer electronics environments. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (TS8), 2.9mm × 1.6mm × 0.8mm profile, exposed pad optional, RoHS-compliant lead-free finish (LTDGJ marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive analog supply | 2.35V–3.6V main power rail; also sets analog input common-mode if using internal reference (not applicable to TS8 variant). |
| VREF (Pin 2) | External reference input | Defines full-scale analog input range (0V to VREF); bypass required with 2.2μF capacitor for stability and noise rejection. |
| GND (Pin 3) | Analog ground | Primary return path for analog circuitry; must connect directly to solid ground plane to minimize noise coupling. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; accepts 0V to VREF signals; high-impedance (±1μA leakage) enables direct sensor connection. |
| OVDD (Pin 5) | Digital output supply | Independent 1V–VDD rail for SDO driver; decouples digital switching noise from analog section and supports mixed-voltage system interfacing. |
| SDO (Pin 6) | Three-state serial data output | MSB-first 12-bit conversion result followed by trailing zeros; enters Hi-Z when CONV is high or during sleep mode. |
| SCK (Pin 7) | Serial clock input | Accepts up to 10MHz clock (tSCK ≥ 100ns); data valid on falling edge; timing-critical for synchronization with host controller. |
| CONV (Pin 8) | Convert start input | Active-high edge-triggered control; rising edge initiates conversion, falling edge enables SDO output and powers up device from sleep. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (10μs max), enabling deterministic real-time control loops without pipeline delay. |
| Automatic sleep mode | Enters 0.1μA sleep state after each conversion when CONV remains high - eliminates need for software-controlled power-down sequences. |
| Dedicated VREF and OVDD pins | Enables independent optimization of analog reference accuracy and digital I/O voltage levels - critical for mixed-signal SoC integration and low-noise sensor front-ends. |
| Reduced full-scale span support | Operates with VREF as low as 1.4V while maintaining 12-bit linearity - allows direct digitization of low-output transducers (e.g., thermocouples, strain gauges) without amplification. |
| Guaranteed operation to 125°C (H-grade) | While LTC2360CTS8#TRPBF is C-grade (0°C–70°C), the same TS8 package supports H-grade variants - simplifies design reuse across temperature grades. |

FAQ
What is the maximum sampling rate supported by the LTC2360CTS8#TRPBF?
The LTC2360CTS8#TRPBF supports a maximum sampling rate of 100ksps, as specified in its datasheet under "Timing Characteristics." This rate is fixed for the LTC2360 variant and differs from the LTC2361 (250ksps) and LTC2362 (500ksps) in the same family. The internal oscillator controls conversion timing, and no external clock is required to achieve this throughput.
Does the LTC2360CTS8#TRPBF require an external reference voltage?
Yes, the LTC2360CTS8#TRPBF requires an external reference voltage applied to the VREF pin (Pin 2). Its analog input range is 0V to VREF, and VREF must be between 1.4V and VDD (2.35V–3.6V). Unlike the 6-lead S6 variants, the TS8 package does not use VDD as the reference - VREF is mandatory and must be bypassed with a 2.2μF capacitor.
What is the purpose of the OVDD pin on the LTC2360CTS8#TRPBF?
The OVDD pin (Pin 5) supplies power to the SDO output driver independently of VDD. It accepts 1V to VDD, enabling the LTC2360CTS8#TRPBF to interface directly with 1.8V, 2.5V, or 3V digital logic without level shifters. This separation prevents digital switching noise from coupling into the analog supply and improves system-level noise immunity.
How does the LTC2360CTS8#TRPBF enter and exit sleep mode?
The LTC2360CTS8#TRPBF automatically enters sleep mode after conversion completion when the CONV pin remains high, drawing only 0.1μA typical supply current. To exit sleep mode, drive CONV low: this powers up the internal circuitry, and after the acquisition time (tACQ = 2μs max), the device is ready for the next conversion triggered by a rising CONV edge.
Is the LTC2360CTS8#TRPBF pin-compatible with other members of the LTC236x family in the TS8 package?
Yes, all LTC2360/LTC2361/LTC2362 variants in the TS8 package share identical pinouts, including VDD, VREF, GND, AIN, OVDD, SDO, SCK, and CONV assignments. This allows drop-in replacement across sampling rates (100/250/500ksps) without PCB layout changes - provided the application's timing, power, and performance requirements align with the selected variant.
