Product details
Overview
LTC2362CS6#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), SPI/MICROWIRE-compatible 3-wire serial interface, no data latency, and is optimized for battery-powered portable instrumentation and sensor interfaces.
For engineers reviewing the LTC2362CS6#TRMPBF datasheet, LTC2362CS6#TRMPBF pinout, LTC2362CS6#TRMPBF application, or LTC2362CS6#TRMPBF equivalent, key selection criteria include its 500ksps throughput with 73dB SNR, 12-bit no-missing-codes resolution, TSOT-23-6 footprint compatibility, low-power sleep mode timing, and VDD-referenced input range - all critical for compact, high-speed, low-power data acquisition designs.
Technical Context
The LTC2362CS6#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 S6-package configuration ties VREF internally to VDD, eliminating external reference components while maintaining 0V–VDD analog input range and 342μV LSB resolution.
Timing is fully synchronous to the external SCK clock, with data valid on SDO after CONV↓ (16ns), MSB-first 12-bit serial output followed by trailing zeros, and automatic Hi-Z transition on SDO after CONV↑ (6ns). Sleep mode activation requires only CONV held high post-conversion, reducing IDD to 0.1μA without external control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and deterministic code spacing for precision measurement. |
| Sampling Rate | 500ksps maximum - enables real-time capture of signals up to 250kHz Nyquist bandwidth without undersampling artifacts. |
| SNR | 73dB at fIN = 100kHz - corresponds to ~0.32LSB RMS noise, supporting sub-1mV signal fidelity in 3V full-scale systems. |
| Supply Current | 1.1mA at 500ksps, 0.1μA in sleep - enables microamp-level system standby power when sampling intervals exceed 1ms. |
| Integral Linearity | ±0.25LSB typical - ensures < ±1mV absolute error over 3V span, critical for calibrated sensor front-ends. |
| Analog Input Range | 0V to VDD (2.35V–3.6V) - eliminates need for external level-shifting or reference buffers in single-supply sensor interfaces. |
| Package | 6-lead TSOT-23 (2.9mm × 1.6mm × 0.8mm) - supports high-density PCB layouts in handheld and wearable devices. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 2.9mm × 1.6mm × 0.8mm body, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and internal reference source | Supplies core ADC and defines full-scale analog input range (0V to VDD); requires 2.2μF ceramic bypass to GND. |
| GND (Pin 2) | Analog and digital ground reference | Must connect directly to solid ground plane; shared return for VDD, AIN, and digital I/O to minimize noise coupling. |
| AIN (Pin 3) | Single-ended analog input | Accepts DC-coupled signals from 0V to VDD; high-impedance input (±1μA leakage) allows direct transducer connection. |
| SCK (Pin 4) | Serial clock input | Controls data shift timing; SDO transitions on falling edge; max 50MHz clock rate supports fast readout. |
| SDO (Pin 5) | Three-state serial data output | Outputs 12-bit MSB-first conversion result followed by trailing zeros; enters Hi-Z state when CONV is high. |
| CONV (Pin 6) | Convert start and output enable control | Rising edge initiates conversion; low state enables SDO and clocks out data; high state forces sleep mode. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (2μs), enabling deterministic real-time control loops. |
| VDD-referenced architecture | Eliminates external voltage reference and associated cost/area; maintains 12-bit linearity across 2.35V–3.6V supply range. |
| Automatic sleep mode | IDD drops to 0.1μA within 2μs of conversion completion when CONV remains high - no software or external circuitry required. |
| High-impedance analog input | Input leakage ≤ ±1μA and capacitance ≤ 4pF during conversion - minimizes loading on high-Z sensors like thermistors or piezoelectrics. |
| SPI/MICROWIRE compatibility | 3-wire interface (CONV, SCK, SDO) with standard timing - interoperable with common MCU peripherals without protocol translation. |

FAQ
What is the maximum sampling rate supported by the LTC2362CS6#TRMPBF?
The LTC2362CS6#TRMPBF supports a maximum sampling rate of 500ksps, with guaranteed 2μs minimum throughput time (tTHROUGHPUT) and 1.5μs conversion time (tCONV) across its full operating temperature range of 0°C to 70°C. This rate is maintained with 73dB SNR at 100kHz input frequency and requires SCK clock up to 50MHz.
Does the LTC2362CS6#TRMPBF require an external voltage reference?
No, the LTC2362CS6#TRMPBF does not require an external voltage reference. In the S6 package configuration, it uses VDD as the internal reference source, establishing a 0V to VDD analog input range. This eliminates external reference components and reduces BOM cost and board area while maintaining ±0.25LSB integral linearity.
How does the LTC2362CS6#TRMPBF achieve ultra-low power consumption?
The LTC2362CS6#TRMPBF achieves ultra-low power consumption through automatic sleep mode activation: when CONV remains high after conversion completion, supply current drops to 0.1μA typical within 2μs. At 500ksps, it draws only 1.1mA, and current scales linearly downward at lower rates - enabling multi-year battery life in duty-cycled sensor nodes.
What is the analog input voltage range for the LTC2362CS6#TRMPBF?
The analog input voltage range for the LTC2362CS6#TRMPBF is 0V to VDD, where VDD operates from 2.35V to 3.6V. This VDD-referenced architecture supports direct connection to single-supply sensors and transducers without level-shifting circuitry, delivering 342μV LSB resolution across the full supply range.
Is the LTC2362CS6#TRMPBF pin-compatible with other members of the LTC236x family?
Yes, the LTC2362CS6#TRMPBF shares identical pinout and footprint with LTC2360CS6#TRMPBF and LTC2361CS6#TRMPBF in the S6 package. All three use the same 6-lead TSOT-23 layout (VDD, GND, AIN, SCK, SDO, CONV), enabling drop-in replacement across 100ksps, 250ksps, and 500ksps variants without PCB redesign.
