Product details
Overview
LTC2361IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 250ksps successive-approximation ADC in a 6-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 0.75mA 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 guaranteed operation from –40°C to +85°C. It is used in battery-powered data acquisition front-ends where compact size and micro-power performance are critical.
For engineers reviewing the LTC2361IS6#TRMPBF datasheet, LTC2361IS6#TRMPBF pinout, LTC2361IS6#TRMPBF application, or LTC2361IS6#TRMPBF equivalent, key selection criteria include sampling rate vs. power trade-off, reference architecture (VDD-referenced), TSOT-23-6 footprint constraints, and compatibility with 3V microcontroller I/O levels.
Technical Context
The LTC2361IS6#TRMPBF implements an internal sample-and-hold with aperture jitter of 0.3ns and acquisition time of 1μs, enabling accurate sampling of signals up to 2MHz full-power bandwidth. Its switched-capacitor SAR core delivers 73dB SNR and –85dB THD at 49kHz input frequency, with integral linearity error of ±0.25LSB typical.
It uses a 3-wire serial interface: CONV initiates conversion on rising edge and enables SDO output on falling edge; SCK clocks out 12-bit MSB-first data on falling edges; SDO enters high-impedance state when CONV is high. No external reference or output supply is required - VDD serves as both analog reference and digital supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function for control-loop feedback and precision measurement. |
| Sampling Rate | 250ksps maximum - supports real-time monitoring of fast transients in motor control or sensor fusion systems. |
| Supply Current | 0.75mA at 250ksps, 0.1μA in sleep mode - enables >1-year battery life in intermittent-sampling IoT nodes. |
| SNR / THD | 73dB SNR, –85dB THD at 49kHz - sufficient for 11.2 ENOB in vibration sensing and audio-level signal conditioning. |
| Analog Input Range | 0V to VDD (2.35V–3.6V) - eliminates need for external reference or level-shifting when interfacing with 3V sensors. |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation and automotive cabin electronics environments. |
| Package | 6-lead TSOT-23 (1.6mm × 2.9mm) - fits space-constrained PCB layouts in handheld medical or portable test equipment. |
Pinout & Package
Package: 6-lead plastic TSOT-23 (S6), 1.6mm × 2.9mm footprint, 0.95mm height, thermal resistance θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and reference voltage source | Supplies analog and digital circuitry; defines full-scale 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 all supplies and analog input. |
| AIN (Pin 3) | Single-ended analog input | Accepts 0V to VDD signals with ±1μA leakage; high-impedance input (4pF during conversion) enables direct sensor connection. |
| SCK (Pin 4) | Serial clock input | Accepts up to 25MHz clock; data valid on falling edge; timing-critical for synchronization with host MCU. |
| SDO (Pin 5) | Three-state serial data output | Outputs 12-bit MSB-first conversion result followed by trailing zeros; high-Z when CONV = high. |
| CONV (Pin 6) | Convert start and SDO enable control | Rising edge initiates conversion; falling edge enables SDO output; must be driven rail-to-rail (GND/VDD) to minimize leakage current. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (4μs max), eliminating pipeline delay in closed-loop control. |
| Automatic sleep mode | Enters 0.1μA sleep state after each conversion if CONV remains high - reduces average power by >99% at low duty-cycle sampling. |
| VDD-referenced architecture | Eliminates external reference component and associated cost, board area, and drift - ideal for cost-sensitive portable designs. |
| High-impedance analog input | 4pF input capacitance during conversion and ±1μA leakage allow direct connection to piezoelectric sensors or thermopiles without buffer amplifiers. |
| SPI/MICROWIRE compatibility | Uses standard 3-wire protocol with no CS pin required - simplifies interface to ARM Cortex-M, PIC, or MSP430 microcontrollers. |

FAQ
What is the maximum sampling rate of the LTC2361IS6#TRMPBF?
The LTC2361IS6#TRMPBF supports a maximum sampling rate of 250ksps. This is fixed by its internal oscillator and architecture - no external clock is required to achieve this rate. At lower rates, supply current scales down automatically due to built-in sleep mode activation after each conversion, making the LTC2361IS6#TRMPBF highly efficient across variable throughput demands.
Does the LTC2361IS6#TRMPBF require an external reference voltage?
No, the LTC2361IS6#TRMPBF does not require an external reference. It uses VDD as the reference source, resulting in a full-scale input range of 0V to VDD (2.35V–3.6V). This eliminates external reference components, reduces BOM cost and board area, and avoids reference drift - a key advantage of the LTC2361IS6#TRMPBF in battery-powered and portable applications.
What is the operating temperature range for the LTC2361IS6#TRMPBF?
The LTC2361IS6#TRMPBF is specified for operation from –40°C to +85°C (Industrial grade). This range is explicitly confirmed in the ordering information table for part number LTC2361IS6#TRMPBF and is fully characterized for all electrical parameters including INL, SNR, and supply current. It meets requirements for industrial control, automotive cabin electronics, and outdoor deployed sensors.
How does the serial interface of the LTC2361IS6#TRMPBF work?
The LTC2361IS6#TRMPBF uses a 3-wire SPI/MICROWIRE-compatible interface: CONV starts conversion on rising edge and enables SDO on falling edge; SCK clocks data out on falling edges; SDO outputs 12-bit MSB-first data followed by trailing zeros. No chip select is needed - SDO goes high-Z when CONV is high. The interface requires no configuration registers, simplifying firmware integration for the LTC2361IS6#TRMPBF.
What is the supply current of the LTC2361IS6#TRMPBF during active and sleep modes?
The LTC2361IS6#TRMPBF draws 0.75mA typical supply current during active conversion at 250ksps, and only 0.1μA in sleep mode when CONV remains high after conversion. This automatic transition to ultra-low-power sleep significantly reduces average current in duty-cycled applications - a defining feature of the LTC2361IS6#TRMPBF that enables multi-year battery operation in remote sensors.
