Product details
Overview
LTC2361HS6#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 125°C. It is used in high-speed, low-power sensor digitization in automotive engine control units.
For engineers reviewing the LTC2361HS6#TRMPBF datasheet, LTC2361HS6#TRMPBF pinout, LTC2361HS6#TRMPBF application, or LTC2361HS6#TRMPBF equivalent, key selection criteria include its 250ksps throughput, 73dB SNR at 124kHz input, 12-bit no-missing-codes resolution, TSOT-23-6 thermal performance up to 125°C, and VDD-referenced analog input architecture requiring no external reference.
Technical Context
The LTC2361HS6#TRMPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to enforce precise 250ksps sampling. Its conversion timing is deterministic: 4μs total throughput time (1μs acquisition + 3μs conversion), with SDO output enabled on CONV low and data valid on falling SCK edge.
It operates exclusively in VDD-referenced mode (S6 package), eliminating VREF and OVDD pins-thus fixing full-scale range to 0V–VDD and digital I/O swing to VDD. This simplifies layout but requires matching host logic voltage to VDD, unlike the TS8 variant which supports independent OVDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes-guarantees monotonic transfer function for closed-loop control feedback. |
| Sampling Rate | 250ksps maximum-supports anti-aliasing filter cutoff ≤125kHz and real-time monitoring of fast transients. |
| SNR | 73dB at 124kHz input-enables accurate digitization of medium-bandwidth sensor signals (e.g., knock sensors, pressure transducers). |
| Supply Current | 0.75mA at 250ksps, 0.1μA in sleep-reduces average power to ~1.9mW at 1ksps, ideal for duty-cycled battery systems. |
| Integral Linearity | ±0.25LSB typical-limits gain/offset drift-induced error to <0.006% FS across temperature, critical for calibration stability. |
| Operating Temp | –40°C to 125°C-qualified for under-hood automotive applications without derating or external thermal management. |
| Input Range | 0V to VDD (2.35V–3.6V)-eliminates need for external reference or level-shifting circuitry in single-supply systems. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1.6mm × 1.6mm × 0.55mm, thermal pad optional, θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and reference source | Supplies core logic and defines full-scale analog input range (0V–VDD); must be bypassed with 2.2μF ceramic capacitor. |
| GND (Pin 2) | Analog/digital ground reference | Single ground connection for both analog input and digital interface; requires direct tie to solid ground plane. |
| AIN (Pin 3) | Analog input node | High-impedance (20pF), single-ended input referenced to GND; accepts 0V–VDD signals without external buffering. |
| SCK (Pin 4) | Serial clock input | Asynchronous master clock for data readout; SDO transitions on falling edge; max 25MHz frequency. |
| SDO (Pin 5) | Three-state serial data output | Outputs 12-bit MSB-first conversion result followed by trailing zeros; tri-states when CONV is high. |
| CONV (Pin 6) | Convert trigger and output enable | 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 (4μs), enabling tight real-time control loops without pipeline delay compensation. |
| Automatic sleep mode | Enters 0.1μA sleep automatically after conversion completion if CONV remains high-no software command required. |
| VDD-referenced architecture | Eliminates external reference and OVDD supply rails, reducing BOM count and PCB area in space-constrained modules. |
| Guaranteed 125°C operation | Specified performance maintained over full industrial+automotive temperature range without derating or guard-banding. |
| SPI/MICROWIRE compatibility | Direct interface with standard microcontrollers (e.g., ARM Cortex-M, Renesas RL78) 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, no guaranteed 125°C operation, 6-pin SOT-23 package | Lower sampling rate and narrower temp range limit use in high-dynamic automotive or avionics environments | Select when cost sensitivity outweighs speed/temp requirements and 5V logic compatibility is needed. |
| MAX11100ETT+ | 250ksps, 12-bit, 2.7–3.6V, –40°C to 125°C, 6-pin TDFN-but uses external reference and lacks VDD-referenced mode | Requires external reference and decoupling, increasing BOM and layout complexity vs. LTC2361HS6#TRMPBF's self-contained architecture | Select when reference flexibility (e.g., 2.048V precision ref) is prioritized over board space and simplicity. |

FAQ
What is the maximum sampling rate of the LTC2361HS6#TRMPBF?
The LTC2361HS6#TRMPBF has a maximum sampling rate of 250ksps, with guaranteed timing performance including 1μs acquisition time and 3μs conversion time. This rate is fixed by the internal oscillator and does not require external clocking. At lower rates, supply current scales down automatically due to built-in sleep mode activation after each conversion.
Does the LTC2361HS6#TRMPBF require an external reference voltage?
No, the LTC2361HS6#TRMPBF does not require an external reference voltage. As an S6-package device, it uses VDD as the reference source, establishing a 0V to VDD analog input range. This eliminates the need for external reference components, simplifying design and reducing bill-of-materials cost compared to TS8 variants like LTC2361HTS8#TRMPBF.
What is the operating temperature range of the LTC2361HS6#TRMPBF?
The LTC2361HS6#TRMPBF is rated for operation from –40°C to 125°C, with all electrical specifications guaranteed across this full range. This H-grade qualification makes it suitable for under-hood automotive applications, industrial motor drives, and avionics systems where sustained high junction temperatures are expected.
How does the LTC2361HS6#TRMPBF achieve low power consumption?
The LTC2361HS6#TRMPBF achieves low power consumption through automatic entry into sleep mode (0.1μA typical) immediately after conversion completion when CONV remains high. Its 0.75mA operational current at 250ksps drops proportionally at lower sampling rates, enabling average power as low as 1.9mW at 1ksps-ideal for battery-powered and thermally constrained systems.
Is the LTC2361HS6#TRMPBF pin-compatible with other devices in the LTC236x family?
No, the LTC2361HS6#TRMPBF is not pin-compatible with TS8-package variants (e.g., LTC2361HTS8#TRMPBF) due to differing pin counts and functions-S6 has 6 pins (VDD, GND, AIN, SCK, SDO, CONV), while TS8 adds VREF and OVDD. Within the S6 group, pinout is identical across LTC2360HS6#TRMPBF, LTC2361HS6#TRMPBF, and LTC2362HS6#TRMPBF, enabling footprint reuse with rate-specific firmware configuration.
