Product details
Overview
LTC2362HTS8#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 500ksps successive-approximation ADC in an 8-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 1.1mA typical supply current at full rate and 0.1μA sleep current. It features a dedicated external reference input (VREF), independent digital output supply (OVDD: 1V to VDD), SPI/MICROWIRE-compatible serial interface, and guaranteed operation from –40°C to 125°C. It is used in high-speed, low-power sensor digitization in automotive engine control units.
For engineers reviewing the LTC2362HTS8#TRPBF datasheet, LTC2362HTS8#TRPBF pinout, LTC2362HTS8#TRPBF application, or LTC2362HTS8#TRPBF equivalent, key selection criteria include its 500ksps throughput with 73dB SNR, TSOT-23-8 thermal performance up to 125°C, VREF-supported 1.4V–VDD input span, and OVDD-driven 1.0V–3.6V logic compatibility for mixed-voltage systems.
Technical Context
The LTC2362HTS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, internal oscillator-controlled conversion timing, and automatic power-down after each conversion. Its TSOT-23-8 package provides separate VREF and OVDD pins, enabling flexible analog input scaling and independent digital I/O voltage control.
It supports SPI/MICROWIRE 3-wire serial communication with MSB-first 12-bit data + trailing zeros, CONV-triggered acquisition, and SDO three-state control synchronized to CONV and SCK edges. Timing parameters are fully characterized across –40°C to 125°C, including tACQ = 0.5μs, tCONV = 1.5μs, and tTHROUGHPUT = 2μs.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive analog supply | 2.35V–3.6V main supply; defines internal bias and sets max VREF; requires 2.2μF ceramic bypass to GND. |
| VREF (Pin 2) | External reference input | Defines full-scale analog input range (0V to VREF); supports 1.4V–VDD range; requires 2.2μF bypass. |
| GND (Pin 3) | Analog ground reference | Single-point connection to solid ground plane; separates analog return from digital noise sources. |
| AIN (Pin 4) | Analog input | Single-ended, high-impedance input referenced to GND; accepts 0V to VREF; CIN = 4pF during conversion. |
| OVDD (Pin 5) | Digital output supply | Independent supply for SDO driver (1.0V–VDD); enables level-shifting to 1.8V/2.5V/3.3V logic domains. |
| SDO (Pin 6) | Serial data output | Three-state, MSB-first 12-bit output + trailing zeros; enabled by CONV low; driven by OVDD voltage. |
| SCK (Pin 7) | Serial clock input | Accepts up to 50MHz clock; data valid on falling edge; setup/hold times defined relative to CONV. |
| CONV (Pin 8) | Convert trigger input | Active-high edge initiates conversion; low level enables SDO; controls sleep/wake state and power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (2μs), eliminating pipeline delay in closed-loop control. |
| Dedicated VREF and OVDD | Enables independent optimization of analog accuracy (via stable VREF) and digital interoperability (via OVDD). |
| Automated sleep mode | Draws only 0.1μA when CONV remains high post-conversion - reduces average power proportionally to sampling duty cycle. |
| High-impedance analog input | AIN leakage ≤ ±1μA and CIN = 4pF during conversion - minimizes loading on high-Z sensors and transducers. |
| Guaranteed 125°C operation | All DC and AC specs validated across –40°C to +125°C - eliminates derating assumptions in thermal design. |

FAQ
What is the maximum sampling rate supported by the LTC2362HTS8#TRPBF?
The LTC2362HTS8#TRPBF supports a maximum sampling rate of 500ksps, with guaranteed timing performance including tTHROUGHPUT = 2μs, tACQ = 0.5μs, and tCONV = 1.5μs across its full –40°C to +125°C operating range. This enables accurate digitization of signals up to 250kHz without aliasing in Nyquist-limited applications.
Does the LTC2362HTS8#TRPBF require an external reference voltage?
Yes - the LTC2362HTS8#TRPBF uses a dedicated VREF pin (Pin 2) to define its analog input range (0V to VREF), supporting VREF values from 1.4V to VDD. This allows precise ratiometric measurements and direct interfacing with low-span sensors without gain amplification, unlike VDD-referenced variants.
How does the OVDD pin on the LTC2362HTS8#TRPBF improve system design?
The OVDD pin (Pin 5) on the LTC2362HTS8#TRPBF independently powers the SDO output driver, allowing logic-level compatibility with 1.0V–VDD digital systems (e.g., 1.8V FPGAs or 2.5V MCUs) without external level shifters. This simplifies mixed-voltage board design and ensures clean signal integrity across voltage domains.
What power-saving features does the LTC2362HTS8#TRPBF offer?
The LTC2362HTS8#TRPBF automatically enters sleep mode after each conversion when CONV remains high, reducing supply current from 1.1mA (active) to 0.1μA (sleep). This feature enables proportional power scaling with sampling duty cycle - critical for battery-powered and thermally constrained applications.
Is the LTC2362HTS8#TRPBF compatible with standard SPI interfaces?
Yes - the LTC2362HTS8#TRPBF implements a 3-wire SPI/MICROWIRE-compatible serial interface with CONV as chip select, SCK as clock, and SDO as data output. It transmits 12-bit MSB-first data followed by trailing zeros, with timing fully specified for interoperability with common microcontrollers and DSPs.
