Product details
Overview
LTC2392CLX-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with ±4.096V fully differential input range, ±2LSB INL (max), 94dB SNR (typ), and integrated 4.096V reference. It operates from a single 5V supply and supports both parallel and serial interfaces, targeting high-fidelity data acquisition in medical imaging and industrial instrumentation.
For engineers reviewing the LTC2392CLX-16#PBF datasheet, LTC2392CLX-16#PBF pinout, LTC2392CLX-16#PBF application, or LTC2392CLX-16#PBF equivalent, key selection considerations include guaranteed no missing codes at 16 bits, internal reference tempco ≤ ±20ppm/°C, 1300ns conversion time, 110mW power dissipation at full rate, and LQFP-48 package compatibility with 0°C to 70°C operation.
Technical Context
The LTC2392CLX-16#PBF employs a charge-redistribution SAR architecture with a precision internal 4.096V reference buffer and on-chip common-mode output (VCM = 2.048V). Its differential input stage accepts ±VREF swing with 70dB CMRR and 50MHz –3dB bandwidth, enabling accurate digitization of fast, high-dynamic-range signals without external amplification in many cases.
Conversion is initiated by a CNVST falling edge; an internal oscillator eliminates external clock dependency. The device delivers zero-cycle latency in both parallel and serial modes, with BUSY signaling completion and RD/CS enabling synchronized readout. Nap and sleep power-down modes reduce current to 250µA and 22µA respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full 65,536-code dynamic range with no missing codes across temperature. |
| Sampling Rate | 500ksps - enables real-time capture of signals up to 250kHz Nyquist bandwidth. |
| SNR | 94dB (typ) at fIN = 20kHz - corresponds to ~15.6 effective bits (ENOB) for low-noise signal fidelity. |
| INL | ±2LSB (max) - ensures monotonicity and linearity critical for closed-loop control and calibration. |
| Reference | Integrated 4.096V ±0.5% initial accuracy, ±20ppm/°C max tempco - eliminates need for external reference in cost-sensitive designs. |
| Power Dissipation | 110mW at 500ksps - balances performance and thermal management in dense PCB layouts. |

Pinout & Package
48-lead 7mm × 7mm plastic LQFP package (LX variant), RoHS-compliant, with exposed pad (Pin 49) soldered to ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 5, 7, 20, 35, 41, 44, 48, EP 49) | Ground reference | All analog/digital grounds tied to solid ground plane; exposed pad must be soldered for thermal dissipation and noise reduction. |
| AVP (Pins 2, 40, 45, 46, 47) | Analog power supply | 4.75V–5.25V supply for analog core; requires local 0.1µF + 10µF ceramic bypassing to GND. |
| DVP (Pins 3, 19) | Digital power supply | 4.75V–5.25V supply for digital logic; bypassed identically to AVP. |
| OVP (Pin 18) | I/O interface power | 1.8V–5V supply for parallel/serial bus drivers; bypassed with 4.7µF ceramic to OGND. |
| IN+, IN– (Pins 43, 42) | Differential analog inputs | Accept ±4.096V differential swing; input impedance modeled as 40pF || 50Ω during acquisition. |
| REFOUT / REFIN (Pins 37, 38) | Reference I/O | Internal 4.096V reference output (REFOUT) tied to REFIN for self-referenced operation; REFSENSE left open. |
| CNVST (Pin 34) | Conversion start | Falling-edge-triggered; initiates sample-and-hold and conversion independently of CS/RD timing. |
| BUSY (Pin 29) | Conversion status | Active-high pulse indicates conversion in progress; falling edge serves as data-ready strobe. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay or cycle latency | Enables deterministic real-time sampling in closed-loop systems without output buffering or timing uncertainty. |
| Parallel and serial interface support | Configurable via SER/PAR pin; serial mode uses SDIN/SDOUT/SCLK with MSB-first, 16-clock transfer. |
| Internal conversion clock | Removes requirement for external master clock, simplifying system timing design and reducing jitter sensitivity. |
| Two output formats | Offset binary or two's complement selectable via OB/2C pin-supports direct integration with DSP/FPGA sign-handling logic. |
| Temperature grade C (0°C to 70°C) | Validated performance across commercial temperature range; suitable for lab equipment and non-mission-critical industrial use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1MSPS, single-ended input only; no integrated reference; requires external 4.096V ref. | Suitable for space-constrained designs where single-ended drive simplifies layout but demands external reference and driver. | Select when higher throughput (1MSPS) is required and system already includes precision reference; verify INL (±1.5LSB) and SNR (92.5dB) meet target ENOB. |
| AD7606BSTZ | 16-bit, 200kSPS, 8-channel simultaneous sampling; integrated reference; parallel+SPI interface. | Optimized for multi-channel synchronized acquisition (e.g., motor phase current sensing), not single-channel high-speed streaming. | Choose for 8-channel systems needing channel-to-channel isolation and simultaneous hold; accept lower per-channel rate (200kSPS) vs. LTC2392CLX-16#PBF's 500ksps. |
Compared with ADS8860IDRCT and AD7606BSTZ, the LTC2392CLX-16#PBF uniquely combines 500ksps single-channel throughput, integrated ±20ppm/°C reference, differential input flexibility, and zero-latency parallel/serial interfaces-making it optimal for high-fidelity, low-jitter, single-signal digitization where board space and reference complexity must be minimized.

FAQ
What is the operating temperature range for the LTC2392CLX-16#PBF?
The LTC2392CLX-16#PBF is specified for 0°C to 70°C ambient operation (Commercial grade). This is confirmed by the "C" suffix in the part number and the LX package ordering table. It is not rated for extended industrial (–40°C to 85°C) or high-reliability (–40°C to 125°C) ranges; those require LTC2392ILX-16#PBF or LTC2392HLX-16#PBF variants respectively.
Does the LTC2392CLX-16#PBF require an external reference?
No, the LTC2392CLX-16#PBF includes a precision internal 4.096V reference with ±0.5% initial accuracy and ±20ppm/°C max temperature coefficient. To use it, connect REFOUT to REFIN and leave REFSENSE unconnected. An external reference may be used for higher accuracy, but is not required for standard operation of the LTC2392CLX-16#PBF.
How does the LTC2392CLX-16#PBF handle data readout in parallel versus serial mode?
The LTC2392CLX-16#PBF uses the SER/PAR pin to select interface mode: low enables 16-bit parallel output on D0–D15 pins; high enables serial output via SDOUT with SCLK and CS. In both modes, BUSY falling edge signals data readiness, and RD/CS together enable bus access. Serial mode supports daisy-chaining using SDIN.
What is the power consumption of the LTC2392CLX-16#PBF at full speed?
At 500ksps with all supplies at 5V, the LTC2392CLX-16#PBF dissipates 110mW typical (135mW max), drawing 22mA–27mA from AVP/DVP and 35mA from OVP. In nap mode (conversion complete, digital inputs held), power drops to 175µW; in full sleep mode (PD high), it falls to 250µW - values confirmed in the Power Requirements section of the datasheet.
Can the LTC2392CLX-16#PBF interface directly with 1.8V logic systems?
Yes. The LTC2392CLX-16#PBF supports 1.8V to 5V I/O voltage levels via the OVP supply pin. Digital outputs (D0–D15, SDOUT, BUSY, etc.) are level-shifted to match OVP, and digital inputs (RD, CS, CNVST, etc.) accept thresholds compatible with 1.8V logic (VIH ≥ 0.8×OVP). This allows seamless interfacing with low-voltage FPGAs or microcontrollers without level translators.
