Product details
Overview
LTC2362CTS8#TRPBF from Analog Devices (acquired Linear Technology) is a 12-bit, 500ksps successive-approximation ADC in an 8-lead TSOT-23 package, operating from a single 2.35V–3.6V supply with 1.1mA typical supply current at full rate. It features dedicated VREF and OVDD pins, 0V–VREF analog input range (down to 1.4V full-scale), SPI/MICROWIRE-compatible 3-wire serial interface, and no data latency - used in high-speed, low-power sensor digitization for portable instrumentation.
For engineers reviewing the LTC2362CTS8#TRPBF datasheet, LTC2362CTS8#TRPBF pinout, LTC2362CTS8#TRPBF application, or LTC2362CTS8#TRPBF equivalent, key selection criteria include its 500ksps throughput with 73dB SNR at 100kHz input, 12-bit no-missing-codes performance, sleep-mode current of 0.1μA, and TSOT-23-8 compatibility with 1V–3.6V digital output swing via OVDD.
Technical Context
The LTC2362CTS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, controlled by an internal oscillator enabling precise 500ksps sampling without external clock dependency. Its timing is defined by fixed tACQ = 0.5μs and tCONV = 1.5μs, yielding 2μs minimum throughput time.
It supports flexible reference configuration: VREF (1.4V to VDD) sets full-scale analog range, while OVDD (1.0V to VDD) independently biases SDO output voltage level - enabling direct interfacing with 1.8V/2.5V/3.0V logic systems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function and deterministic code mapping across full temperature range. |
| Sampling Rate | 500ksps maximum - enables real-time capture of signals up to 250kHz Nyquist bandwidth with undersampling capability. |
| SNR | 73dB at fIN = 100kHz - corresponds to ~0.32LSB RMS transition noise, supporting high-fidelity signal reconstruction. |
| Supply Current | 1.1mA at 500ksps, 0.1μA in sleep mode - enables battery operation with duty-cycled acquisition schemes. |
| Integral Linearity | ±1 LSB max - ensures <0.025% full-scale error for precision measurement applications. |
| Reference Range | VREF = 1.4V to VDD - allows reduced-span operation for improved resolution on low-voltage sensors (e.g., 342μV LSB at 1.4V span). |
| Digital Output Supply | OVDD = 1.0V to VDD - decouples logic interface voltage from analog supply, simplifying mixed-voltage system integration. |
Pinout & Package
Package: 8-lead plastic TSOT-23 (TS8), 0°C to 70°C operating temperature range, JEDEC MO-220 compatible, 2.9mm × 1.6mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog power supply | 2.35V–3.6V supply for core ADC and sample-and-hold; defines analog ground reference plane. |
| VREF (Pin 2) | External reference input | 1.4V–VDD reference voltage source; sets full-scale analog input range (0V to VREF) and determines LSB size. |
| GND (Pin 3) | Analog ground | Primary return path for analog circuitry; must connect directly to solid ground plane to minimize noise coupling. |
| AIN (Pin 4) | Analog input | Single-ended input referenced to GND; accepts 0V–VREF range; high-impedance (±1μA leakage) for direct sensor connection. |
| OVDD (Pin 5) | Digital output supply | 1.0V–VDD supply for SDO driver; sets logic-high level independently of VDD, enabling 1.8V/2.5V/3.0V MCU interfacing. |
| SDO (Pin 6) | Serial data output | Three-state MSB-first SPI output; driven only when CONV is low; outputs 12-bit conversion result followed by trailing zeros. |
| SCK (Pin 7) | Serial clock input | Asynchronous clock for data readout; SDO transitions on falling edge; supports up to 50MHz clock frequency. |
| CONV (Pin 8) | Convert control input | Active-high signal initiating conversion on rising edge; falling edge enables SDO and triggers data readout sequence. |
Key Features
| Feature | Design Value |
|---|---|
| No data latency | Conversion result available immediately after tTHROUGHPUT (2μs), eliminating pipeline delay in closed-loop control systems. |
| Independent OVDD | Enables SDO to drive 1.8V logic even when VDD = 3.3V, removing need for external level translators in mixed-supply designs. |
| Reduced-span operation | Supports VREF as low as 1.4V, achieving 342μV LSB resolution - ideal for low-output transducers without gain amplification. |
| Automatic sleep mode | Enters 0.1μA sleep state automatically after conversion completion if CONV remains high, minimizing average power in burst-sampling applications. |
| Guaranteed operation to 125°C | Specified over –40°C to 125°C for H-grade variants; C-grade (LTC2362CTS8#TRPBF) validated 0°C to 70°C with same electrical specs. |

FAQ
What is the maximum sampling rate supported by the LTC2362CTS8#TRPBF?
The LTC2362CTS8#TRPBF supports a maximum sampling rate of 500ksps, verified across the full 0°C to 70°C operating temperature range. This is achieved using an internal oscillator, eliminating the need for external clock circuitry. At this rate, the device draws 1.1mA typical supply current from a 3V supply and delivers 73dB SNR at 100kHz input frequency.
Does the LTC2362CTS8#TRPBF require an external reference voltage?
Yes, the LTC2362CTS8#TRPBF requires an external reference voltage applied to the VREF pin (Pin 2). VREF sets the full-scale analog input range (0V to VREF) and can be configured from 1.4V up to VDD. The device does not include an internal reference; using VDD as reference is only supported in the 6-lead S6-package variants, not the TS8 package of LTC2362CTS8#TRPBF.
Can the LTC2362CTS8#TRPBF interface directly with a 1.8V microcontroller?
Yes, the LTC2362CTS8#TRPBF can interface directly with a 1.8V microcontroller by setting OVDD (Pin 5) to 1.8V. This configures the SDO output driver to swing between 0V and 1.8V, matching the microcontroller's logic thresholds without external level-shifting circuitry. VDD and VREF may remain at 3.0V or 3.3V to maintain analog performance.
What is the sleep-mode current consumption of the LTC2362CTS8#TRPBF?
The LTC2362CTS8#TRPBF draws 0.1μA typical supply current in sleep mode, measured at 0°C to 70°C. Sleep mode activates automatically after conversion completion when the CONV pin remains high. This ultra-low quiescent current enables energy-efficient burst-sampling architectures in battery-powered applications.
Is the LTC2362CTS8#TRPBF pin-compatible with other members of the LTC236x family?
No, the LTC2362CTS8#TRPBF is not pin-compatible with LTC2360 or LTC2361 in the TS8 package - all three share identical 8-pin TSOT-23 pinouts (VDD, VREF, GND, AIN, OVDD, SDO, SCK, CONV) and functionally equivalent pin assignments. However, performance parameters differ: LTC2362 offers 500ksps/1.1mA, LTC2361 is 250ksps/0.75mA, and LTC2360 is 100ksps/0.5mA.
