Product details
Overview
LTC2362IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 500ksps successive-approximation ADC in a 6-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 single-ended analog input (0V to VDD), no data latency, SPI/MICROWIRE-compatible serial interface, and is rated for –40°C to +85°C operation. It targets compact, battery-powered sensor acquisition systems requiring high throughput per watt.
For engineers reviewing the LTC2362IS6#TRMPBF datasheet, LTC2362IS6#TRMPBF pinout, LTC2362IS6#TRMPBF application, or LTC2362IS6#TRMPBF equivalent, key selection criteria include its 500ksps sampling rate with 73dB SNR, 12-bit no-missing-codes resolution, TSOT-23-6 footprint compatibility, low-power sleep mode timing, and single-supply operation without external reference.
Technical Context
The LTC2362IS6#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to guarantee fixed 2μs conversion time and 1.5μs acquisition time. Its analog input is referenced directly to GND and VDD, eliminating need for external reference or level-shifting circuitry in S6-package configurations.
Timing is controlled by active-high CONV signal: rising edge initiates conversion and places SDO in Hi-Z; falling edge enables SDO output and synchronizes 12-bit MSB-first serial data transfer on SCK falling edges. No pipeline delay or data latency occurs - output is valid immediately after conversion completes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and full 4096-code range for precision measurement. |
| Sampling Rate | 500ksps maximum - supports real-time acquisition of signals up to 250kHz Nyquist bandwidth. |
| SNR | 73dB at fIN = 100kHz - enables >11.8 effective bits for high-fidelity signal digitization. |
| Supply Current | 1.1mA at 500ksps, 0.1μA in sleep - enables microamp-level system standby power when idle. |
| Integral Linearity | ±1 LSB max - ensures <0.025% full-scale error for calibrated sensor interfacing. |
| Analog Input Range | 0V to VDD (2.35V–3.6V) - simplifies direct connection to unbuffered sensors and transducers. |
| Operating Temp | –40°C to +85°C - qualified for industrial and automotive cabin environments. |
Pinout & Package
Package: 6-lead plastic TSOT-23 (S6), 1.6mm × 1.6mm × 0.55mm profile, exposed pad optional, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply rail | 2.35V–3.6V analog/digital core supply; also defines full-scale input range (0V to VDD). |
| GND (Pin 2) | Analog ground reference | Must connect directly to solid ground plane; serves as analog input reference and digital return. |
| AIN (Pin 3) | Analog input | Single-ended, high-impedance (±1μA leakage) input referenced to GND; accepts 0V to VDD. |
| SCK (Pin 4) | Serial clock input | Accepts up to 50MHz clock; data shifts out on falling edge; timing-critical for SDO setup/hold. |
| SDO (Pin 5) | Three-state serial data output | MSB-first 12-bit output followed by trailing zeros; Hi-Z when CONV = high; driven by VDD. |
| CONV (Pin 6) | Convert control input | Active-high signal: rising edge starts conversion; falling edge enables SDO and initiates data readout. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tCONV (1.5μs); eliminates buffering and timing uncertainty in closed-loop systems. |
| Auto-sleep power management | Draws only 0.1μA when CONV remains high post-conversion - reduces average power in burst-mode sensing. |
| Single-supply operation | Eliminates need for dual supplies or external reference; simplifies PCB layout and BOM for space-constrained designs. |
| Small-footprint TSOT-23-6 | 1.6mm × 1.6mm body enables integration into wearables, IoT nodes, and portable test equipment. |
| SPI/MICROWIRE compatibility | Interoperates with standard MCU/DSP serial peripherals without protocol translation or glue logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 200ksps max, 2.7–5.25V supply, 1.25mW at 200ksps, 6-pin SOT-23 package | Lower speed and wider supply range; lacks sleep mode; lower SNR (70dB) | Choose for legacy 5V systems where 200ksps suffices and sleep mode is unnecessary. |
| MAX11100ETT+ | 500ksps, 12-bit, 2.7–3.6V, 1.5mW, 6-pin TDFN, built-in reference buffer | Includes internal reference buffer but requires external 2.5V reference; higher supply sensitivity | Choose when precise ratiometric measurement against stable external reference is required and TDFN is acceptable. |

FAQ
What is the maximum sampling rate supported by the LTC2362IS6#TRMPBF?
The LTC2362IS6#TRMPBF supports a maximum sampling rate of 500ksps, with guaranteed 2μs minimum throughput time and 1.5μs conversion time. This rate is maintained across the full –40°C to +85°C operating temperature range and 2.35V–3.6V supply voltage range, enabling reliable high-speed acquisition in demanding environments.
Does the LTC2362IS6#TRMPBF require an external reference voltage?
No, the LTC2362IS6#TRMPBF does not require an external reference voltage. In the S6 package (used by LTC2362IS6#TRMPBF), VDD serves as the reference, establishing a 0V to VDD analog input range. This eliminates external reference components and simplifies design for cost-sensitive, space-constrained applications.
How does the sleep mode function in the LTC2362IS6#TRMPBF?
The LTC2362IS6#TRMPBF automatically enters sleep mode after conversion completion when the CONV pin remains high, reducing supply current to 0.1μA typical. Sleep mode shuts down internal bias currents while maintaining the sample-and-hold in hold state. Power-up and acquisition resume within tACQ (0.5μs) after CONV goes low.
What digital interface protocol does the LTC2362IS6#TRMPBF use?
The LTC2362IS6#TRMPBF uses a 3-wire SPI/MICROWIRE-compatible serial interface with CONV, SCK, and SDO lines. It outputs 12-bit MSB-first data followed by trailing zeros, synchronized to SCK falling edges. No CS pin is required - CONV doubles as chip select and conversion trigger.
Is the LTC2362IS6#TRMPBF pin-compatible with other members of the LTC236x family?
Yes, the LTC2362IS6#TRMPBF shares identical pinout and footprint with LTC2360IS6#TRMPBF and LTC2361IS6#TRMPBF in the S6 package. All three are drop-in replacements differing only in maximum sampling rate (100ksps/250ksps/500ksps) and corresponding supply current - enabling scalable design reuse across performance tiers.
