Product details
Overview
LTC2383HMS-16#PBF 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 2.5 V VDD supply and supports 1.8 V–5 V I/O logic levels via separate OVDD, enabling direct interfacing with diverse host processors in high-speed data acquisition systems.
For engineers reviewing the LTC2383HMS-16#PBF datasheet, LTC2383HMS-16#PBF pinout, LTC2383HMS-16#PBF application, or LTC2383HMS-16#PBF equivalent, key selection considerations include guaranteed no-missing-codes operation across –40°C to +125°C, daisy-chain SPI compatibility, internal conversion clock, zero-cycle latency, and differential input drive requirements for medical imaging and industrial process control.
Technical Context
The LTC2383HMS-16#PBF 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 external clock dependency for timing-critical systems.
Conversion is initiated by a rising edge on CNV; BUSY goes high at start and low upon completion. The device automatically powers down between conversions, scaling quiescent current to sampling rate - 110 µA at 1 Msps (H-grade), 0.5 µA in power-down mode - while maintaining full specification compliance over its extended temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 discrete output codes with guaranteed no missing codes across full temperature range. |
| Sampling Rate | 1 Msps - enables real-time digitization of signals up to ~30 MHz input bandwidth without undersampling. |
| SNR | 92 dB (typ, fIN = 20 kHz) - supports >15 ENOB for precision measurement applications requiring high dynamic range. |
| INL | ±2 LSB (max) - ensures monotonicity and linearity critical for closed-loop control and calibration-sensitive instrumentation. |
| Supply Voltage (VDD) | 2.5 V (2.375–2.625 V) - single low-noise rail simplifies power design; decoupling requires 10 µF ceramic capacitor. |
| Reference Input | 2.5 V external REF (2.4–2.6 V) - defines ±2.5 V differential input range; draws up to 910 µA at 1 Msps, requiring low-impedance bypass (47 µF X5R). |
| Operating Temperature | –40°C to +125°C - qualified for harsh environments including engine control units and downhole oil & gas sensors. |
Pinout & Package
Package: 16-lead plastic MSOP (4 mm × 5 mm), exposed pad not present in MSOP variant; thermal resistance θJA = 110°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | High enables daisy-chain SPI mode (RDL/SDI becomes serial data input); low enables normal bus-enable mode. |
| VDD (2) | Digital core supply | 2.5 V supply for ADC logic and CDAC; must be bypassed to GND with 10 µF ceramic capacitor. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce; all must connect to low-impedance PCB ground plane. |
| 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 | 2.5 V external reference defining full-scale range; requires 47 µF X5R ceramic capacitor directly at pin. |
| CNV (9) | Convert trigger | Rising edge initiates conversion; device powers down while CNV remains high, reducing idle power. |
| BUSY (11) | Conversion status indicator | Active-high open-drain output signaling conversion in progress; used for timing synchronization or interrupt generation. |
| RDL/SDI (12) | Serial interface control/data input | In Normal Mode (CHAIN = low): bus enable; in Chain Mode (CHAIN = high): serial data input for daisy-chained readback. |
| SCK (13) | Serial clock input | Accepts 100 MHz max clock (10 ns period); controls timing of SDO data output and SDI sampling (setup/hold verified at 1.71–5.25 V OVDD). |
| SDO (14) | Serial data output | 2's complement 16-bit result shifted MSB-first on SCK rising edges; tri-state controlled by RDL/SDI in Normal Mode. |
| OVDD (15) | I/O interface supply | 1.71–5.25 V supply setting logic level for SCK, RDL/SDI, SDO, BUSY; decoupled with 0.1 µF capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay / zero cycle latency | Enables deterministic real-time control loops without output code buffering or timing uncertainty. |
| Auto power-down between conversions | Reduces average power to 13 µW at 1 ksps - ideal for battery-powered portable instrumentation with burst sampling. |

|---|---|---|---|
| AD7960BCPZ-RL7 | 18-bit, 5 Msps, 2.5 V supply, ±2.048 V input range, 99 dB SNR, requires external reference and clock. | Higher resolution and speed but larger package (32-lead LFCSP), higher power (34 mW), and no auto power-down. | Select when >16-bit resolution and >1 Msps throughput are required; verify layout support for faster timing and tighter noise control. |
| LTC2378-20IMS#PBF | 20-bit, 1 Msps, 2.5 V supply, ±2.5 V input range, 104 dB SNR, same MSOP-16 package, –40°C to +125°C rating. | Higher resolution and SNR but higher power (29 mW), no daisy-chain mode, and stricter reference drive requirements. | Choose for ultra-high-precision applications where 20-bit linearity outweighs power and interface flexibility trade-offs. |

FAQ
What is the maximum operating temperature for the LTC2383HMS-16#PBF?
The LTC2383HMS-16#PBF is rated for continuous operation from –40°C to +125°C, meeting the H-grade specification. All key AC and DC parameters - including ±2 LSB INL, 92 dB SNR, and 13 mW power - are guaranteed across this full range, validated per JEDEC JESD22-A108.
Does the LTC2383HMS-16#PBF require an external clock source?
No, the LTC2383HMS-16#PBF integrates an internal oscillator that sets conversion timing. External clocking is unnecessary for basic operation; only the SCK signal is needed for serial data transfer. This eliminates clock jitter sensitivity and simplifies system-level timing design.
Can the LTC2383HMS-16#PBF interface directly with a 1.8 V microcontroller?
Yes. The LTC2383HMS-16#PBF supports 1.8 V logic levels via its OVDD pin, which accepts 1.71 V to 5.25 V. When OVDD = 1.8 V, VIH = 1.44 V and VIL = 0.36 V, ensuring reliable communication with 1.8 V MCUs without level-shifting circuitry.
What reference voltage IC is recommended for use with the LTC2383HMS-16#PBF?
The LTC6652-2.5 is explicitly recommended in the datasheet: a 2.5 V precision reference with 0.05% initial accuracy and 5 ppm/°C drift, fully specified over –40°C to +125°C. It provides sufficient current and low noise to maintain <0.5 LSB reference deviation at 1 Msps with proper 47 µF X5R bypassing.
How does the daisy-chain mode work on the LTC2383HMS-16#PBF?
When CHAIN = high, the LTC2383HMS-16#PBF enters daisy-chain mode: RDL/SDI becomes SDI (serial data input), and SDO shifts out the previous device's data on the same SCK. Up to 16 devices can be chained using one SCK and one SDO line, reducing GPIO count and PCB routing complexity in multi-channel systems.
