Product details
Overview
LTC2377IDE-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with ±0.5LSB INL max, 97dB SNR at 2kHz, and digital gain compression (DGC) support. It operates from a 2.5V analog supply and accepts 2.5V–5.1V external reference voltage, delivering full differential input range ±VREF while consuming only 6.8mW at full speed - used in high-speed data acquisition systems requiring precision, low power, and extended temperature operation.
For engineers reviewing the LTC2377IDE-16#TRPBF datasheet, LTC2377IDE-16#TRPBF pinout, LTC2377IDE-16#TRPBF application, or LTC2377IDE-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, daisy-chain SPI interface compatibility across 1.8V–5V logic levels, internal conversion clock, and operation over –40°C to +85°C in a 4mm × 3mm DFN package.
Technical Context
The LTC2377IDE-16#TRPBF implements a fully differential SAR architecture with charge redistribution capacitor DAC and internal oscillator, eliminating external timing dependencies. Its conversion cycle has zero latency and no pipeline delay, enabling deterministic real-time sampling for closed-loop control and transient capture.
Digital Gain Compression (DGC) redefines full-scale input range from ±VREF to 0.1×VREF to 0.9×VREF when REF/DGC is grounded - preserving 16-bit resolution while allowing single-supply amplifier driving (e.g., LT6350 from +5.5V). The device supports both normal and daisy-chain SPI modes via CHAIN pin control, with BUSY-synchronized readout and RDL/SDI dual-function I/O.
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 | 500ksps - enables real-time capture of signals up to 250kHz Nyquist bandwidth without undersampling. |
| SNR | 97dB (typ, fIN = 2kHz, VREF = 5V) - supports >15.8 effective bits (ENOB) for high-fidelity signal digitization. |
| INL | ±0.5LSB (max) - ensures monotonic transfer function and accurate end-point calibration in precision measurement. |
| Power Dissipation | 6.8mW at 500ksps - enables battery-operated instrumentation with thermal headroom in compact layouts. |
| Reference Range | 2.5V to 5.1V - allows flexible system-level scaling (e.g., 5V ref yields 152µV/LSB step size). |
| Operating Temp | –40°C to +85°C - qualified for industrial process control and portable test equipment environments. |
Pinout & Package
Package: 16-lead (4mm × 3mm) plastic DFN with exposed pad (Pin 17 = GND), RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CHAIN) | Chain Mode Selector | Low = normal SPI mode (RDL/SDI = bus enable); high = daisy-chain mode (RDL/SDI = serial data input). |
| 2 (VDD) | Analog Supply | 2.5V ±62.5mV supply for core ADC; bypassed with 10µF ceramic capacitor to GND. |
| 4,5 (IN+, IN–) | Differential Analog Inputs | Accept ±VREF fully differential input; 45pF sampling capacitance and 40Ω switch resistance define drive requirements. |
| 7 (REF) | Reference Input | 2.5V–5.1V external reference; requires 47µF X5R ceramic decoupling at pin. |
| 8 (REF/DGC) | Reference/Digital Gain Control | Tied to REF = standard ±VREF range; tied to GND = DGC mode (0.1–0.9×VREF swing). |
| 9 (CNV) | Convert Trigger | Rising edge initiates acquisition and conversion; powers up ADC from auto-power-down state. |
| 11 (BUSY) | Conversion Status Indicator | High during conversion; falls low when 16-bit result is ready on SDO for readout. |
| 12 (RDL/SDI) | Serial Interface Dual-Function Pin | In normal mode: bus enable; in chain mode: serial data input from upstream ADC. |
| 13 (SCK) | Serial Clock Input | Supports up to 100MHz clock (10ns period); defines timing for SDO data shift-out MSB-first. |
| 14 (SDO) | Serial Data Output | 2's complement 16-bit result shifted out MSB-first on SCK rising edges; tri-state when RDL = low. |
| 15 (OVDD) | I/O Supply | 1.71V–5.25V logic supply; sets SPI voltage level compatibility (1.8V/2.5V/3.3V/5V). |
Key Features
| Feature | Design Value |
|---|---|
| Digital Gain Compression (DGC) | Enables single-supply amplifier driving (e.g., LT6350 from +5.5V) by mapping full-scale input to 0.1–0.9×VREF, preserving 16-bit resolution without negative rail. |
| No Pipeline Delay / Zero Cycle Latency | Delivers deterministic conversion completion timing - critical for time-triggered control loops and synchronized multi-channel sampling. |
| Internal Conversion Clock | Eliminates need for external master clock source or precise timing coordination; simplifies PCB layout and reduces BOM count. |
| Auto Power-Down Between Conversions | Reduces idle power to 0.9µA (typ), scaling dynamically with sample rate - extends battery life in portable instrumentation. |
| Daisy-Chain SPI Mode | Allows cascading multiple LTC2377IDE-16#TRPBF devices on shared SCK/SDO lines using CHAIN and RDL/SDI pins - minimizes GPIO usage in multi-channel systems. |

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 34mW at full speed. | Higher resolution/speed but significantly higher power and board space; lacks integrated DGC for single-supply driver simplification. | Select when >16-bit resolution and >500ksps throughput are mandatory, and thermal/power budget permits. |
| ADS8860IDRCT | 16-bit, 1MSPS, 2.5–5V supply, no DGC, SPI-only interface (no daisy-chain), 12.5mW at 1MSPS. | Higher speed but no DGC or chain mode; limited to 0°C to +70°C industrial grade; lower SNR (92.5dB typ). | Select for cost-sensitive, single-channel, room-temperature applications where daisy-chain and extended temp are not required. |

FAQ
What is the operating temperature range of the LTC2377IDE-16#TRPBF?
The LTC2377IDE-16#TRPBF is rated for operation from –40°C to +85°C, meeting industrial-grade reliability requirements. This range is confirmed in the Absolute Maximum Ratings table and applies to all electrical specifications marked with the "l" symbol in the datasheet, including INL, SNR, and power consumption.
Does the LTC2377IDE-16#TRPBF support daisy-chaining with other ADCs?
Yes, the LTC2377IDE-16#TRPBF supports daisy-chain mode via the CHAIN pin (Pin 1). When CHAIN is high, the RDL/SDI pin functions as serial data input, allowing multiple LTC2377IDE-16#TRPBF devices to share one SPI bus. The SDO output of one device connects to the RDL/SDI input of the next, with timing coordinated by the shared SCK and BUSY signals.
How does Digital Gain Compression (DGC) work in the LTC2377IDE-16#TRPBF?
Digital Gain Compression (DGC) in the LTC2377IDE-16#TRPBF is enabled by grounding the REF/DGC pin (Pin 8). This remaps the full-scale input range from ±VREF to 0.1×VREF to 0.9×VREF - e.g., 0.5V to 4.5V with a 5V reference - allowing single-supply amplifiers like the LT6350 to drive the inputs without a negative rail while preserving full 16-bit resolution.
What is the minimum and maximum reference voltage supported by the LTC2377IDE-16#TRPBF?
The LTC2377IDE-16#TRPBF supports an external reference voltage (REF pin, Pin 7) from 2.5V to 5.1V. At 2.5V, LSB size is 76µV; at 5.1V, LSB size is 155µV. Reference voltage directly scales input range, SNR, and THD performance - all dynamic specs in the datasheet are characterized across this full range.
Is the LTC2377IDE-16#TRPBF pin-compatible with other variants in the LTC2377 family?
Yes, the LTC2377IDE-16#TRPBF shares identical pinout and footprint with all 16-lead DFN variants (e.g., LTC2377CDE-16#TRPBF, LTC2377HDE-16#TRPBF), differing only in temperature grade (–40°C to +85°C for "I", 0°C to +70°C for "C", –40°C to +125°C for "H"). Electrical specifications are identical except where explicitly temperature-limited (e.g., SNR degradation above 85°C).
