Product details
Overview
LTC2360HTS8#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 at full rate and 0.1μA sleep current. It features a dedicated external reference input (VREF), independent digital output supply (OVDD), and SPI/MICROWIRE-compatible serial interface. It is designed for high-precision, low-power sensor interfacing in automotive and industrial systems requiring operation from –40°C to 125°C.
For engineers reviewing the LTC2360HTS8#TRPBF datasheet, LTC2360HTS8#TRPBF pinout, LTC2360HTS8#TRPBF application, or LTC2360HTS8#TRPBF equivalent, key selection criteria include guaranteed high-temp performance (–40°C to 125°C), 73dB SNR at 49kHz, 12-bit no-missing-codes resolution, 1.4V–VDD reference range, and TSOT-23-8 pin compatibility across the LTC236x family.
Technical Context
The LTC2360HTS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to enforce fixed 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 connection without gain stages.
It employs a 3-wire serial interface where CONV initiates conversion on the rising edge and enables SDO output on the falling edge; data is clocked out MSB-first on SDO's falling SCK edge. OVDD (1V to VDD) independently sets digital output swing, enabling interoperability with 1.8V/2.5V/3V logic domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and full code coverage over temperature. |
| Sampling Rate | 100ksps maximum - defines real-time acquisition bandwidth for DC to ~49kHz signals. |
| SNR | 73dB at fIN = 49kHz - enables >11.8 effective bits for precision measurement applications. |
| Supply Current | 0.5mA typical at 100ksps; 0.1μA in sleep mode - supports battery-powered operation with duty-cycled sampling. |
| Reference Range | 1.4V to VDD (TS8 package) - allows flexible scaling for low-voltage sensors while maintaining 342μV LSB step size at 1.4V span. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and harsh industrial environments. |
| Digital I/O Supply | OVDD = 1.0V to VDD - decouples logic interface voltage from analog supply, enabling mixed-voltage system integration. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (TS8), 2.9mm × 1.6mm × 0.8mm, thermal pad optional, θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog supply input | 2.35V–3.6V main supply; also defines analog input common-mode range when used as reference in S6 variant (not applicable here). |
| VREF (Pin 2) | External reference input | 1.4V–VDD reference voltage source; sets full-scale analog input range (0V to VREF); requires 2.2μF bypass. |
| GND (Pin 3) | Analog ground | Primary return path for analog circuitry; must connect directly to solid ground plane. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; accepts 0V to VREF signal; high-impedance (±1μA leakage). |
| OVDD (Pin 5) | Digital output supply | 1.0V–VDD supply for SDO driver; sets logic-high level independently of VDD; requires 2.2μF bypass. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first SPI-compatible output; driven only when CONV is low; transitions on falling SCK edge. |
| SCK (Pin 7) | Serial clock input | Input clock synchronizing data transfer; max 10MHz; timing-critical for t4 (8ns data valid after SCK↓) and t7 (4ns hold). |
| CONV (Pin 8) | Convert control input | Active-high conversion trigger; rising edge starts sampling; falling edge enables SDO and initiates data readout. |

FAQ
What is the maximum sampling rate of the LTC2360HTS8#TRPBF?
The LTC2360HTS8#TRPBF has a maximum sampling rate of 100ksps, enforced by its internal oscillator. This rate is guaranteed over the full –40°C to +125°C operating temperature range. At lower rates, supply current scales proportionally, dropping to 0.1μA in sleep mode between conversions. The throughput time is fixed at 10μs per conversion, including acquisition and conversion phases.
Does the LTC2360HTS8#TRPBF require an external reference voltage?
Yes, the LTC2360HTS8#TRPBF requires an external reference voltage applied to the VREF pin (Pin 2). Its reference range is 1.4V to VDD, allowing flexible scaling for low-voltage sensors. Unlike the S6-package variants, the TS8 package does not use VDD as the default reference-VREF must be supplied externally and bypassed with a 2.2μF capacitor to GND for optimal noise performance.
Can the LTC2360HTS8#TRPBF interface with a 1.8V microcontroller?
Yes, the LTC2360HTS8#TRPBF can interface directly with a 1.8V microcontroller via its OVDD pin (Pin 5), which sets the SDO output voltage swing independently of VDD. By connecting OVDD to 1.8V, the SDO logic-high level is guaranteed ≥1.6V (VDD – 0.2V), meeting standard 1.8V VIH requirements. SCK and CONV inputs remain compatible with 1.8V logic levels per their VIH/VIL specs.
What is the guaranteed operating temperature range for the LTC2360HTS8#TRPBF?
The LTC2360HTS8#TRPBF is rated for continuous operation from –40°C to +125°C, denoted by the "H" grade suffix. This specification is fully tested and guaranteed across all electrical parameters-including INL, SNR, and supply current-making it suitable for under-hood automotive, industrial motor control, and other high-reliability applications where ambient temperatures exceed 105°C.
How does the LTC2360HTS8#TRPBF achieve ultra-low power consumption?
The LTC2360HTS8#TRPBF achieves ultra-low power through automatic sleep mode activation after each conversion: when CONV remains high post-conversion, bias circuits shut down, reducing supply current to just 0.1μA typical. Active current is only 0.5mA at 100ksps. Designers minimize power further by driving CONV rail-to-rail (GND/VDD) and holding SCK static during idle periods-both practices suppress unnecessary input buffer current.
