Product details
Overview
LTC2393ILX-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 1 Msps successive approximation register (SAR) analog-to-digital converter with ±4.096 V fully differential input range, ±2 LSB INL (max), and 94.2 dB SNR (typ) at 20 kHz input - designed for high-dynamic-range data acquisition in industrial process control and medical imaging systems.
For engineers reviewing the LTC2393ILX-16#PBF datasheet, LTC2393ILX-16#PBF pinout, LTC2393ILX-16#PBF application, or LTC2393ILX-16#PBF equivalent, key selection criteria include guaranteed no missing codes at 16 bits, internal 4.096 V reference with ±20 ppm/°C tempco, dual parallel/serial interface support, and operation across –40°C to +85°C in 48-lead LQFP packaging.
Technical Context
The LTC2393ILX-16#PBF implements a charge-redistribution SAR architecture with differential comparator and 16-bit CDAC, enabling precise digitization of ±VREF inputs without pipeline delay or cycle latency. Its internal oscillator fixes conversion time at 600 ns, eliminating external clock dependency for timing-critical sampling.
It supports both offset binary and two's complement output formats via OB/2C pin, and byte-swapped parallel output via BYTESWAP - all while maintaining 140 mW power dissipation at full 1 Msps throughput and offering nap/sleep power-down modes for dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale quantization into 65,536 discrete levels with no missing codes over temperature. |
| Sampling Rate | 1 Msps - enables real-time capture of signals up to 500 kHz Nyquist bandwidth with minimal latency. |
| SNR | 94.2 dB (typ) at fIN = 20 kHz - delivers >15.6 effective number of bits (ENOB) for precision measurement applications. |
| INL | ±2 LSB (max) - ensures monotonicity and linearity critical for closed-loop control and calibration-sensitive systems. |
| Reference | Internal 4.096 V ±0.5% initial accuracy, ±20 ppm/°C max tempco - eliminates need for external reference in most industrial designs. |
| Supply | Single 5 V AVP/DVP (4.75–5.25 V); I/O voltage 1.8–5 V OVP - simplifies mixed-voltage system integration. |
| Power Dissipation | 140 mW at 1 Msps - balances speed and thermal budget in space-constrained embedded instrumentation. |
Pinout & Package
48-lead 7 mm × 7 mm plastic LQFP package (JEDEC MS-026), rated for –40°C to +85°C operating temperature. Exposed pad not present in LQFP variant (unlike QFN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN– | Differential analog input | Accepts ±4.096 V differential signal; requires matched drive for optimal CMRR and distortion performance. |
| CNVST | Conversion start trigger | Falling-edge–activated; initiates sample-and-hold acquisition and conversion sequence independently of CS/RD. |
| BUSY | Conversion status indicator | High during conversion; falling edge signals valid data ready for read - usable as synchronous data-ready clock. |
| CS, RD | Parallel interface enable | Both low to enable 16-bit parallel output bus (D0–D15); supports high-speed latch-based data capture. |
| SER/PAR | Interface mode select | Logic low = parallel mode (D0–D15 active); logic high = serial mode (SDOUT, SCLK, SDIN active). |
| REFOUT / REFIN | Reference I/O pair | Internally tied for internal reference use; REFIN accepts external 2.5–4.096 V reference when REFOUT grounded. |
| PD, RESET | Power and logic control | PD high enters low-power nap/sleep mode; RESET high forces digital reset and Hi-Z outputs. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay | Zero-cycle latency ensures deterministic timing between CNVST edge and BUSY assertion - essential for real-time control loops. |
| Dual interface flexibility | Hardware-selectable parallel (16-bit bus) or serial (SPI-compatible 16-bit shift-out) reduces PCB routing complexity and supports legacy or space-constrained designs. |
| Guaranteed 125°C operation | Specified for H-grade (LTC2393HLX-16), but I-grade LTC2393ILX-16#PBF operates reliably up to +85°C with full AC/DC specs maintained. |
| Low aperture jitter | 7 ps RMS - preserves SNR at high input frequencies by minimizing sampling time uncertainty. |
| Configurable output format | OB/2C pin selects offset binary (for unsigned processing) or two's complement (for bipolar signal math) - avoids software sign extension overhead. |
Applications
| Medical Imaging Data Acquisition | High-Speed Industrial ATE |
|---|---|
|

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 |
|---|---|---|---|
| AD7626BCPZ-RL7 | 16-bit, 10 Msps, 2.5 V supply, LVDS/parallel interface; higher speed but requires dual supplies and external reference. | Better suited for high-bandwidth oscilloscope front-ends than industrial control due to power and layout complexity. | Select when >1 Msps sampling is required and system can accommodate 2.5 V analog rail and LVDS termination. |
| ADS8860IPWR | 16-bit, 1 Msps, SPI-only interface, 2.5–5 V supply, no internal reference; 125 mW power, ±1.5 LSB INL (max). | Lower cost and smaller WSON package, but lacks parallel interface and internal reference - increases BOM count. | Prefer for cost-sensitive, SPI-native microcontroller systems where board space is constrained and reference IC is already present. |
Compared with AD7626BCPZ-RL7 and ADS8860IPWR, the LTC2393ILX-16#PBF uniquely combines internal 4.096 V reference, dual parallel/serial interface, and guaranteed ±2 LSB INL in a single 5 V supply LQFP package - reducing design risk in industrial and medical applications demanding proven DC accuracy and timing determinism.

FAQ
What is the operating temperature range for the LTC2393ILX-16#PBF?
The LTC2393ILX-16#PBF is specified for operation from –40°C to +85°C. This industrial-grade temperature range is validated across all AC and DC electrical specifications including INL, SNR, and reference stability - making it suitable for deployment in factory automation and outdoor instrumentation without derating.
Does the LTC2393ILX-16#PBF require an external reference?
No, the LTC2393ILX-16#PBF includes a precision internal 4.096 V reference with ±0.5% initial accuracy and ±20 ppm/°C max temperature coefficient. External reference is optional and only needed when tighter initial accuracy (<0.05%) or lower tempco (<10 ppm/°C) is required - such as in metrology-grade calibration equipment.
How does the parallel interface of the LTC2393ILX-16#PBF operate?
The LTC2393ILX-16#PBF parallel interface activates when SER/PAR = low and both CS and RD are low. It outputs 16-bit data on pins D0–D15 with configurable byte order (via BYTESWAP) and output format (via OB/2C). BUSY falling edge indicates data validity - enabling synchronous latch capture without additional handshaking logic.
Can the LTC2393ILX-16#PBF be used with a 3.3 V microcontroller I/O?
Yes. The LTC2393ILX-16#PBF supports 1.8 V to 5 V digital I/O voltage (OVP), so it interfaces directly with 3.3 V microcontrollers. Set OVP = 3.3 V and bypass OVP to OGND with a 4.7 μF ceramic capacitor. All digital inputs (CS, RD, CNVST, etc.) are 3.3 V–compatible when OVP = 3.3 V.
What power-saving modes does the LTC2393ILX-16#PBF support?
The LTC2393ILX-16#PBF offers two hardware-controlled power-down modes: Nap mode (28 mA typical supply current) and Sleep mode (250 μA typical). Both are activated via the PD pin. Nap mode retains reference and bias states for fast wake-up (<1 μs), while Sleep mode minimizes current for extended idle periods - ideal for battery-operated instruments.
