Product details
Overview
LTC2362CS6#TRPBF from Analog Devices (acquired 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. It features single-ended analog input (0V to VDD), no data latency, SPI/MICROWIRE-compatible serial interface, and sleep mode drawing 0.1μA - enabling high-speed, ultra-low-power sensing in space-constrained battery-operated systems.
For engineers reviewing the LTC2362CS6#TRPBF datasheet, LTC2362CS6#TRPBF pinout, LTC2362CS6#TRPBF application, or LTC2362CS6#TRPBF equivalent, key selection considerations include its 500ksps throughput at 1.1mA, 73dB SNR at 100kHz input, 12-bit no-missing-codes performance, TSOT-23-6 footprint compatibility, and VDD-referenced input architecture requiring no external reference.
Technical Context
The LTC2362CS6#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, using an internal oscillator to guarantee fixed 500ksps sampling without external clock dependency. Its conversion timing is deterministic: 1.5μs conversion time + 0.5μs acquisition time = 2μs minimum throughput time.
It uses VDD as both supply and reference, eliminating VREF pin and simplifying layout versus TS8 variants - but constraining full-scale range to 0V–VDD and limiting resolution scalability below 3.6V. Digital I/O operates at VDD level only, with SDO output swing matching VDD and compatible with 3V logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and full 4096-code dynamic range for precision measurement. |
| Sampling Rate | 500ksps maximum - supports real-time capture of signals up to 250kHz Nyquist bandwidth. |
| SNR | 73dB at fIN = 100kHz - enables >11.8 effective bits for clean signal digitization in noisy environments. |
| Supply Current | 1.1mA at 500ksps, dropping to 0.1μA in sleep mode - reduces average power to ~1.65mW at 100Hz sampling. |
| Integral Linearity | ±1 LSB max - ensures end-point accuracy within ±0.024% of full scale for calibrated sensor interfaces. |
| Analog Input Range | 0V to VDD (2.35V–3.6V) - eliminates need for external reference but requires stable VDD for ratio-metric accuracy. |
| Package | 6-lead TSOT-23 (2.9mm × 1.6mm × 0.8mm) - enables PCB area savings in portable medical, IoT, and wearables designs. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 2.9mm × 1.6mm × 0.8mm, thermal resistance θJA = 250°C/W, rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and reference input | Supplies core logic and defines full-scale analog input range (0V to VDD); must be bypassed with 2.2μF ceramic capacitor to GND. |
| GND (Pin 2) | Analog and digital ground reference | Single ground connection for all internal circuits; requires low-impedance tie to solid ground plane. |
| AIN (Pin 3) | Analog input | Single-ended input referenced to GND; accepts 0V–VDD range; high-impedance (4pF during conversion) enables direct sensor connection. |
| SCK (Pin 4) | Serial clock input | Controls data shift timing; SDO transitions on falling edge; supports up to 50MHz clock frequency for fast readout. |
| 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 start and SDO enable control | Rising edge initiates conversion; falling edge enables SDO output; high state forces sleep mode (0.1μA). |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (2μs), enabling deterministic real-time control loops. |
| Automatic sleep mode | Enters 0.1μA sleep automatically after conversion completion if CONV remains high - critical for duty-cycled battery systems. |
| VDD-referenced architecture | Eliminates external reference and associated routing/decoupling, reducing BOM count and PCB area in cost-sensitive designs. |
| High input impedance | 4pF input capacitance during conversion minimizes loading on high-impedance sources like thermistors or piezoelectric sensors. |
| SPI/MICROWIRE compatibility | 3-wire interface (CONV, SCK, SDO) with no CS pin required - simplifies host MCU GPIO usage and firmware overhead. |

FAQ
What is the maximum sampling rate of the LTC2362CS6#TRPBF?
The LTC2362CS6#TRPBF has a guaranteed maximum sampling rate of 500ksps, with a minimum throughput time of 2μs (1.5μs conversion + 0.5μs acquisition). This rate is internally clocked and does not require an external clock source - the device achieves this performance while drawing only 1.1mA from a 3V supply.
Does the LTC2362CS6#TRPBF require an external voltage reference?
No, the LTC2362CS6#TRPBF does not require an external voltage reference. It uses VDD as the reference, resulting in a 0V to VDD analog input range. This architecture eliminates the need for external reference components and associated decoupling, simplifying design and reducing BOM cost - though it ties measurement accuracy directly to VDD stability.
What package type and dimensions does the LTC2362CS6#TRPBF use?
The LTC2362CS6#TRPBF uses a 6-lead Plastic TSOT-23 (S6) package measuring 2.9mm × 1.6mm × 0.8mm with a thermal resistance θJA of 250°C/W. Its pinout is VDD–GND–AIN–SCK–SDO–CONV, and it is rated for operation from 0°C to 70°C (C-grade), making it suitable for compact consumer and industrial applications.
How does the sleep mode function on the LTC2362CS6#TRPBF?
The LTC2362CS6#TRPBF automatically enters sleep mode after each conversion when the CONV pin remains high, reducing supply current to just 0.1μA typical. In this state, bias currents are shut down and only leakage remains. The device wakes on the falling edge of CONV, completes acquisition in 0.5μs, then performs conversion - enabling ultra-low average power in burst-mode sensing applications.
Is the LTC2362CS6#TRPBF pin-compatible with other members of the LTC236x family?
Yes, the LTC2362CS6#TRPBF shares identical pinout and footprint with the LTC2360CS6#TRPBF and LTC2361CS6#TRPBF in the S6 package. All three are drop-in replacements with identical VDD–GND–AIN–SCK–SDO–CONV mapping, differing only in maximum sampling rate (100ksps/250ksps/500ksps) and corresponding supply current - allowing hardware reuse across performance tiers.
