Product details
Overview
LTC2380HMS-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 2 Msps successive approximation register (SAR) analog-to-digital converter with ±0.6 LSB INL max, 96.2 dB SNR at 2 kHz, and fully differential ±VREF input range (2.5 V to 5.1 V). It operates from a single 2.5 V supply, consumes 19 mW at full speed, and supports digital gain compression (DGC) for single-supply amplifier interfacing - used in high-speed data acquisition systems requiring precision, low power, and extended temperature operation.
For engineers reviewing the LTC2380HMS-16#PBF datasheet, LTC2380HMS-16#PBF pinout, LTC2380HMS-16#PBF application, or LTC2380HMS-16#PBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance across –40°C to +125°C, SPI-compatible serial interface with daisy-chain mode, internal conversion clock, and DGC-enabled 0.5 V to 4.5 V input range with 5 V reference.
Technical Context
The LTC2380HMS-16#PBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, enabling zero-cycle-latency conversions and no pipeline delay. Its internal oscillator eliminates external clock dependency, while auto power-down between conversions scales quiescent current from 9 mA at 2 Msps to 0.9 µA in shutdown.
Digital gain compression (DGC) redefines full-scale mapping to 10–90% of ±VREF (e.g., 0.5 V to 4.5 V with 5 V REF), allowing rail-to-rail input swing compatibility with single-supply op-amps like LT6350-H. The device supports 1.8 V to 5 V I/O logic via dedicated OVDD supply and features configurable chain-mode serial interface for multi-ADC synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonic transfer function and full 65,536-code output range without missing codes. |
| Sampling Rate | 2 Msps - enables real-time digitization of signals up to 1 MHz Nyquist bandwidth with no latency. |
| SNR | 96.2 dB (typ, fIN = 2 kHz, VREF = 5 V) - delivers 15.7 effective bits, critical for high-fidelity signal capture. |
| INL | ±0.6 LSB (max, –40°C to +125°C) - ensures accurate end-point linearity for calibration-sensitive instrumentation. |
| Power Consumption | 19 mW at 2 Msps, 2.25 µW in power-down - supports battery-operated or thermally constrained embedded systems. |
| Input Range | Fully differential ±VREF, VREF = 2.5 V to 5.1 V - allows flexible signal scaling and dynamic range optimization. |
| DGC Function | Enabled by grounding REF/DGC pin - shifts input range to 0.1×VREF to 0.9×VREF, eliminating need for negative supply in front-end amplifiers. |
Pinout & Package
Package: 16-lead MSOP (plastic), 4.0 mm × 3.0 mm footprint, exposed pad not present (DFN variant has exposed GND pad; MSOP does not).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | High enables daisy-chain SPI mode; low enables RDL/SDI bus-enable function - determines serial interface topology. |
| VDD (2) | Analog supply | 2.375 V to 2.625 V, 2.5 V nominal - powers core ADC circuitry; requires 10 µF ceramic bypass to GND. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR in high-speed sampling. |
| IN+, IN– (4,5) | Differential analog inputs | Accept ±VREF input; 45 pF sampling capacitance and 40 Ω switch resistance define acquisition settling behavior. |
| REF (7) | Reference voltage input | 2.5 V to 5.1 V external reference; decoupled with 47 µF X5R capacitor - sets full-scale range and LSB size (152 µV at 5 V). |
| REF/DGC (8) | Reference/DGC control | Tied to GND enables digital gain compression; tied to REF disables DGC - configures input range mapping without hardware change. |
| CNV (9) | Convert trigger | Rising-edge initiated conversion; powers up ADC and starts SAR cycle - supports precise timing control in synchronous systems. |
| BUSY (11) | Conversion status | Active-high open-drain indicator; asserts at CNV↑ and deasserts when result ready - simplifies host timing without polling. |
| RDL/SDI (12) | Serial data control/input | In normal mode: bus enable; in chain mode: serial data input - enables multi-device cascading with shared SCK/SDO lines. |
| SCK (13) | Serial clock | Up to 100 MHz clock (10 ns period); rising-edge sampled - supports high-throughput SPI transfers with minimal interface overhead. |
| SDO (14) | Serial data output | 2's complement 16-bit output, MSB-first; tri-state controlled by RDL/SDI - compatible with standard SPI controllers and FPGA interfaces. |
| OVDD (15) | I/O supply | 1.71 V to 5.25 V - independently sets logic level for all digital pins, enabling mixed-voltage system integration. |

FAQ
What is the operating temperature range of the LTC2380HMS-16#PBF?
The LTC2380HMS-16#PBF is rated for operation from –40°C to +125°C, as confirmed in the "ORDER INFORMATION" table on page 2 of the datasheet. This H-grade specification applies to both parametric performance (e.g., ±0.6 LSB INL, 96.2 dB SNR) and functional operation across the full range, making it suitable for under-hood automotive, downhole, and industrial control applications.
Does the LTC2380HMS-16#PBF require an external clock source?
No, the LTC2380HMS-16#PBF includes an internal oscillator that sets the conversion time, eliminating the need for an external clock. This is explicitly stated in the "DESCRIPTION" section and verified in the "ADC TIMING CHARACTERISTICS" table (tCONV = 278–322 ns, specified over temperature). External clocks are optional only if overriding internal timing for specialized synchronization.
How does digital gain compression (DGC) work on the LTC2380HMS-16#PBF?
Digital gain compression on the LTC2380HMS-16#PBF is enabled by grounding the REF/DGC pin (Pin 8). When active, it remaps the zero-scale code from 0 V to 0.1 × VREF and full-scale code from VREF to 0.9 × VREF, resulting in an effective input range of 0.5 V to 4.5 V with a 5 V reference. This allows driving amplifiers to operate from a single 5.5 V supply without negative rails.
What package type is used for the LTC2380HMS-16#PBF?
The LTC2380HMS-16#PBF uses a 16-lead plastic MSOP package, as clearly indicated in the "ORDER INFORMATION" table (page 2) and "PIN CONFIGURATION" diagram (page 2). It measures 4.0 mm × 3.0 mm, has no exposed thermal pad, and differs from the DFN variant (LTC2380CDE-16#PBF) which includes an exposed GND pad (Pin 17).
Is the LTC2380HMS-16#PBF pin-compatible with other variants in the LTC2380-16 family?
Yes, all LTC2380-16 variants - including LTC2380CMS-16#PBF, LTC2380IMS-16#PBF, and LTC2380HMS-16#PBF - share identical 16-lead MSOP pinouts and electrical functionality. Only the temperature grade differs: C-grade (0°C to 70°C), I-grade (–40°C to 85°C), and H-grade (–40°C to 125°C). Pin compatibility is confirmed by the unified "PIN CONFIGURATION" diagram and consistent pin numbering across all variants.
