Product details
Overview
LTC2383CMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 1 Msps successive approximation register (SAR) analog-to-digital converter with fully differential ±2.5 V input range, 92 dB SNR at 20 kHz, ±2 LSB INL max, and 13 mW power consumption at full speed. It operates from a single 2.5 V supply (VDD), supports 1.8 V–5 V I/O logic (OVDD), and features no pipeline delay or cycle latency-making it suitable for high-speed data acquisition in medical imaging and portable instrumentation.
For engineers reviewing the LTC2383CMS-16#TRPBF datasheet, LTC2383CMS-16#TRPBF pinout, LTC2383CMS-16#TRPBF application, or LTC2383CMS-16#TRPBF equivalent, key selection considerations include guaranteed 16-bit no-missing-codes operation, internal conversion clock, SPI-compatible serial interface with daisy-chain mode, and MSOP-16 package compatibility with industrial temperature range (0°C to 70°C).
Technical Context
The LTC2383CMS-16#TRPBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, sampling the IN+/IN– inputs during acquisition and performing binary-search conversion against fractions of the external 2.5 V reference. Its internal oscillator eliminates need for external clock synchronization, and auto power-down between conversions scales quiescent current from 13 mA at 1 Msps to 0.5 µA in sleep mode.
It uses 2's complement output format over an SPI-compatible serial interface with configurable RDL/SDI pin (mode-selected by CHAIN), BUSY indicator, and SDO timing aligned to SCK rising edges. The device supports both normal bus-enable mode and daisy-chain mode for multi-ADC systems, with guaranteed timing across OVDD = 1.71 V to 5.25 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonic transfer function and no missing codes across full temperature range. |
| Sampling Rate | 1 Msps - enables real-time digitization of signals up to 500 kHz Nyquist bandwidth without undersampling. |
| SNR | 92 dB (typ) at fIN = 20 kHz - ensures >15 ENOB for precision measurement of low-distortion AC waveforms. |
| INL | ±2 LSB (max) - limits integral nonlinearity error to <0.003% FSR, critical for calibration-sensitive applications. |
| Power Dissipation | 13 mW at 1 Msps - enables high-throughput acquisition in thermally constrained portable or embedded systems. |
| Input Range | ±2.5 V fully differential - supports wide dynamic range while rejecting common-mode noise on IN+/IN–. |
| Reference Input | 2.4 V–2.6 V external - requires low-noise, low-drift source (e.g., LTC6652-2.5) to maintain specified DC accuracy. |
Pinout & Package
Package: 16-lead plastic MSOP (4 mm × 5 mm), lead-free, RoHS-compliant. Exposed pad not present in MSOP variant; thermal resistance θJA = 110°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode control input | Selects Normal Mode (RDL/SDI = bus enable) or Daisy-Chain Mode (RDL/SDI = serial data input); determines SDO/RDL functional mapping. |
| VDD (2) | Digital core supply | 2.375 V–2.625 V supply for ADC logic and internal oscillator; bypass with 10 µF ceramic capacitor to GND. |
| GND (3,6,10,16) | Analog/digital ground | Four dedicated ground pins minimize ground bounce and separate return paths for analog, digital, and reference circuits. |
| IN+, IN– (4,5) | Differential analog inputs | Accept ±2.5 V differential signal; input capacitance = 45 pF (sample mode); require low-impedance drive or buffer (e.g., LT6350). |
| REF (7,8) | Reference voltage input | 2.4 V–2.6 V external reference; draws pulsed current up to 910 µA at 1 Msps; bypass with 47 µF X5R ceramic capacitor. |
| CNV (9) | Convert trigger input | Rising-edge–initiated conversion start; high CNV holds device in auto power-down after conversion completion. |
| BUSY (11) | Status output | Active-high open-drain signal indicating conversion in progress; used for handshaking with host controller. |
| RDL/SDI (12) | Configurable I/O | In Normal Mode: bus enable for SDO tri-state; in Chain Mode: serial data input for daisy-chained ADCs. |
| SCK (13) | Serial clock input | Edge-triggered clock (≤100 MHz) synchronizing SDO data output and SDI data capture; timing validated at 1.71 V–5.25 V OVDD. |
| SDO (14) | Serial data output | MSB-first 2's complement output; driven only when enabled via RDL/SDI or chain mode; compatible with 1.8 V–5 V logic levels. |
| OVDD (15) | I/O interface supply | 1.71 V–5.25 V supply setting logic level thresholds for all digital pins; decouple with 0.1 µF ceramic capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Enables deterministic real-time sampling-conversion result available immediately after BUSY deassertion, eliminating FIFO buffering overhead. |
| Daisy-chain SPI mode | Allows cascading multiple LTC2383-16 devices on single SCK/SDO bus, reducing GPIO count and PCB routing complexity in multi-channel systems. |
| Auto power-down | Reduces IDD from 5.2 mA to 0.5 µA between conversions, enabling ultra-low average power in burst-sampling applications (e.g., battery-powered sensors). |
| Guaranteed operation to 125°C | Validated performance across extended temperature range (H-grade), supporting deployment in harsh industrial or automotive under-hood environments. |
| Internal conversion clock | Removes dependency on external clock source jitter and layout sensitivity-simplifies system timing design and improves SNR stability. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7960BCPZ-RL7 | 18-bit, 5 Msps, 1.8 V/5 V dual-supply, LVDS interface; higher resolution/speed but requires external clock and consumes 39 mW. | Used in metrology-grade systems needing >16-bit precision; incompatible pinout and interface protocol. | Select when ENOB >16.2 and throughput >1 Msps are mandatory; accept added layout complexity and power budget impact. |
| LTC2378IMS-18#TRPBF | 18-bit, 1 Msps, same MSOP-16 package, 2.5 V supply, SPI interface; 95.5 dB SNR but 22 mW power and no daisy-chain mode. | Preferred for DC-critical applications like precision weigh scales; lacks CHAIN pin and daisy-chain capability. | Choose for higher DC accuracy and SNR where multi-ADC synchronization is handled externally; verify REF drive capability. |

Yes. The LTC2383CMS-16#TRPBF supports OVDD = 1.8 V, and its digital I/O pins (SCK, RDL/SDI, SDO, BUSY) are fully compatible with 1.8 V logic levels-verified across min/max OVDD (1.71 V–5.25 V) per Electrical Characteristics table. No level-shifting circuitry is required.
What reference voltage IC is recommended for use with the LTC2383CMS-16#TRPBF?
The LTC6652-2.5 is explicitly recommended in the datasheet for the LTC2383CMS-16#TRPBF. It provides 2.5 V output with 0.05% initial accuracy and 5 ppm/°C drift-matching the ADC's 2.4 V–2.6 V REF input range and preserving full 16-bit linearity and SNR performance.
Is the LTC2383CMS-16#TRPBF pin-compatible with other members of the LTC238X-16 family?
Yes-LTC2383CMS-16#TRPBF shares identical pinout, package (MSOP-16), and interface protocol with LTC2382-16 and LTC2381-16. Differences are limited to speed (1/0.5/0.25 Msps) and power (13/6.5/3.25 mW), allowing drop-in replacement where throughput requirements permit.
