Product details
Overview
LTC2376HMS-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter with ±0.5LSB INL max, 97dB SNR at 2kHz, and fully differential ±VREF input range (2.5V–5.1V reference). Operating from a single 2.5V supply and consuming only 3.4mW, it delivers no missing codes at 16 bits and supports digital gain compression (DGC) to enable single-supply amplifier driving - used in high-speed data acquisition systems requiring precision, low power, and extended temperature operation.
For engineers reviewing the LTC2376HMS-16#PBF datasheet, LTC2376HMS-16#PBF pinout, LTC2376HMS-16#PBF application, or LTC2376HMS-16#PBF equivalent, key selection considerations include guaranteed 125°C operation, SPI-compatible daisy-chain interface, internal conversion clock, 16-lead MSOP package, and DGC-enabled 0.5V–4.5V input range with 5V reference.
Technical Context
The LTC2376HMS-16#PBF implements a charge redistribution capacitor DAC (CDAC) architecture with differential comparator, enabling true 16-bit no-missing-codes performance and ±0.5LSB integral linearity over –40°C to +125°C. Its acquisition phase samples differential input voltage onto 45pF internal capacitance through 40Ω switch RON, followed by a 1.9–3µs conversion time set by an internal oscillator - eliminating external clock dependency.
Digital gain compression (DGC) is controlled via the REF/DGC pin: when grounded, it remaps zero-scale from 0V to 0.1·VREF and full-scale from VREF to 0.9·VREF, yielding a usable 0.5V–4.5V input span with 5V reference - preserving full 16-bit resolution while allowing single 5.5V-supply operation of driving amplifiers like the LT6350-H.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
The LTC2376HMS-16#PBF is housed in a 16-lead plastic MSOP package (4.9mm × 3.0mm × 1.1mm), with exposed pad not present (DFN variant has exposed pad; MSOP does not). Pin 1 is CHAIN; pin 2 is VDD; pins 3, 6, 10, and 16 are GND; pin 7 is REF; pin 8 is REF/DGC; pin 9 is CNV; pin 11 is BUSY; pin 12 is RDL/SDI; pin 13 is SCK; pin 14 is SDO; pin 15 is OVDD; pins 4 and 5 are IN+ and IN–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (Pin 1) | Mode selector | Low = normal SPI mode (RDL/SDI = bus enable); high = daisy-chain mode (RDL/SDI = serial data input). |
| VDD (Pin 2) | Analog supply | 2.5V ±62.5mV supply for core ADC; requires 10µF ceramic bypass to GND. |
| IN+, IN– (Pins 4, 5) | Differential analog inputs | Accept ±VREF fully differential signal; 45pF sampling capacitance, 40Ω switch RON. |
| REF (Pin 7) | Reference input | 2.5V–5.1V external reference; decoupled with 47µF X5R ceramic capacitor. |
| REF/DGC (Pin 8) | Function control | Tied to REF → DGC disabled (±VREF range); tied to GND → DGC enabled (0.1–0.9·VREF range). |
| CNV (Pin 9) | Conversion trigger | Rising edge initiates acquisition and conversion; powers up device from auto-power-down state. |
| BUSY (Pin 11) | Status indicator | Active-high open-drain output signaling conversion in progress; logic referenced to VDD. |
| RDL/SDI (Pin 12) | Configurable I/O | In normal mode: bus enable; in chain mode: serial data input for daisy-chained ADCs. |
| SCK (Pin 13) | Serial clock | Accepts 1.8V–5V logic; supports up to 100MHz SCK frequency; controls data shift timing. |
| SDO (Pin 14) | Serial data output | 2's complement 16-bit result shifted MSB-first on SCK rising edges; tri-state when RDL = low. |
| OVDD (Pin 15) | Digital I/O supply | 1.71V–5.25V interface supply; sets logic thresholds; bypassed with 0.1µF capacitor. |
Key Features

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 |
|---|---|---|---|
| AD7960BCPZ-RL7 | 18-bit, 5MSPS, 2.5V supply, no DGC, requires external reference buffer; consumes 39mW at full speed. | Higher resolution/speed but significantly higher power and cost; lacks integrated DGC and 125°C qualification. | Select when ENOB >16.2 bits is required and thermal/power budget permits. |
| LTC2378IMS-18#PBF | 18-bit, 100ksps, same MSOP package, identical DGC and H-grade support, 2.4mW at 100ksps. | Lower throughput but superior resolution; shares pinout, DGC, and temperature rating - drop-in upgrade path for resolution-critical apps. | Select when 100ksps suffices and 18-bit accuracy is mandatory for DC-coupled sensor interfaces. |
Compared with AD7960BCPZ-RL7, the LTC2376HMS-16#PBF trades 2 bits and 20× speed for 11.5× lower power and integrated DGC - making it optimal for thermally constrained, battery-aware, or single-supply amplifier systems. Versus LTC2378IMS-18#PBF, it offers 2.5× higher throughput at cost of 2-bit resolution - ideal for wideband transient capture where speed outweighs static accuracy.

FAQ
What is the maximum operating temperature specification for the LTC2376HMS-16#PBF?
The LTC2376HMS-16#PBF is an H-grade device specified for continuous operation from –40°C to +125°C ambient temperature, with all electrical parameters guaranteed across this full range per the datasheet's "l" notation. This makes the LTC2376HMS-16#PBF suitable for under-hood automotive, downhole oil/gas, and industrial motor drive applications where thermal margins are critical.
How does digital gain compression (DGC) affect the input voltage range of the LTC2376HMS-16#PBF?
When the REF/DGC pin of the LTC2376HMS-16#PBF is tied to GND, DGC is enabled and the effective input range shifts from the standard ±VREF (e.g., –5V to +5V with 5V reference) to 0.1·VREF to 0.9·VREF (e.g., 0.5V to 4.5V). This preserves full 16-bit resolution while allowing the driving amplifier to operate from a single positive supply - a key advantage implemented directly in the LTC2376HMS-16#PBF's digital core.
Does the LTC2376HMS-16#PBF require an external clock source for conversion timing?
No, the LTC2376HMS-16#PBF integrates an internal oscillator that sets the conversion time (1.9–3µs), eliminating the need for an external clock source. This simplifies system timing design and reduces component count - a built-in feature of the LTC2376HMS-16#PBF that enhances reliability in noise-sensitive or space-constrained layouts.
What package type and lead count does the LTC2376HMS-16#PBF use?
The LTC2376HMS-16#PBF uses a 16-lead plastic MSOP package (4.9mm × 3.0mm × 1.1mm body size), with no exposed thermal pad. This surface-mount package is RoHS-compliant and lead-free, matching the footprint of other H-grade Linear/ADI SAR ADCs such as the LTC2378IMS-18#PBF - enabling direct board-level compatibility in multi-tier ADC designs.
Can the LTC2376HMS-16#PBF interface directly with a 1.8V microcontroller SPI port?
Yes, the LTC2376HMS-16#PBF supports 1.8V logic levels on its digital interface: OVDD can be set to 1.8V, and the SCK, RDL/SDI, and SDO pins are fully compatible with 1.8V CMOS thresholds (VIH = 0.8·OVDD, VIL = 0.2·OVDD). This allows direct connection to low-voltage MCUs without level-shifting circuitry - a verified capability of the LTC2376HMS-16#PBF per its absolute maximum and electrical characteristics tables.
