Product details

Overview

LTC2380IMS-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 2 Msps successive approximation register (SAR) analog-to-digital converter with fully differential ±VREF input, 96.2 dB SNR, ±0.6 LSB INL max, and digital gain compression (DGC) support. It operates from a 2.5 V supply, accepts 2.5–5.1 V reference voltage, and delivers no missing codes at 16 bits - ideal for high-speed medical imaging and portable instrumentation requiring precision, low power, and wide dynamic range.

For engineers reviewing the LTC2380IMS-16#PBF datasheet, LTC2380IMS-16#PBF pinout, LTC2380IMS-16#PBF application, or LTC2380IMS-16#PBF equivalent, key selection criteria include guaranteed 125°C operation (I-grade), MSOP-16 package compatibility, SPI-compatible daisy-chain interface, DGC-enabled single-supply amplifier drive, and 19 mW power consumption at full 2 Msps throughput.

Technical Context

The LTC2380IMS-16#PBF implements a charge-redistribution SAR architecture with internal conversion clock, eliminating external timing dependencies. Its fully differential input stage supports ±VREF ranges (2.5–5.1 V) and achieves 34 MHz –3 dB input bandwidth with 4 ps aperture jitter.

Digital Gain Compression (DGC) remaps zero-scale to 0.1·VREF and full-scale to 0.9·VREF when REF/DGC is grounded - enabling rail-to-rail single-supply amplifier operation without resolution loss. The device features auto power-down between conversions, scaling quiescent current from 19 mW (2 Msps) to 19 µW (2 ksps).

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, 5 Msps, 2.5 V supply, no DGC, requires external reference buffer; consumes 39 mW at full rate.	Higher resolution and speed but lacks integrated DGC and consumes >2× power - suited for lab-grade DAQ, not portable systems.	Select AD7960BCPZ-RL7 only when 18-bit resolution and 5 Msps are mandatory and thermal/power budgets allow.
ADS8860IDRCT	16-bit, 1 Msps, 2.5–5 V supply, no DGC, SPI-only (no daisy-chain), 12.5 mW at 1 Msps, 92.5 dB SNR.	Lower speed and SNR; simpler interface but no chain mode or DGC - appropriate for cost-sensitive, lower-bandwidth industrial sensors.	Choose ADS8860IDRCT for non-critical 1 Msps applications where daisy-chain sync and single-supply drive are unnecessary.

Compared with AD7960BCPZ-RL7 and ADS8860IDRCT, the LTC2380IMS-16#PBF uniquely balances 2 Msps throughput, 96.2 dB SNR, DGC-enabled single-supply drive, and 19 mW power - making it optimal for portable, thermally constrained, and multi-channel synchronized systems where resolution, speed, and efficiency must coexist.

FAQ

What is the maximum sampling frequency supported by the LTC2380IMS-16#PBF?

The LTC2380IMS-16#PBF supports a maximum sampling frequency of 2 Msps, with guaranteed timing performance across its full operating temperature range (–40°C to +85°C). This is enabled by an internal oscillator and optimized SAR architecture that eliminates pipeline delay - ensuring each conversion completes within 500 ns, making the LTC2380IMS-16#PBF suitable for real-time signal capture in high-speed control and measurement systems.

Does the LTC2380IMS-16#PBF require an external reference voltage?

Yes, the LTC2380IMS-16#PBF requires an external reference voltage applied to the REF pin, with a specified range of 2.5 V to 5.1 V. The reference must be low-noise and well-decoupled using a 47 µF X5R ceramic capacitor placed close to the REF pin. The LTC2380IMS-16#PBF does not include an internal reference; accuracy and stability depend entirely on the external reference source.

How does Digital Gain Compression (DGC) function in the LTC2380IMS-16#PBF?

Digital Gain Compression (DGC) in the LTC2380IMS-16#PBF is activated by grounding the REF/DGC pin. It digitally remaps the ADC's full-scale input range from ±VREF to 0.1·VREF to 0.9·VREF, enabling the use of single-supply amplifiers (e.g., LT6350 powered from +5.5 V) without sacrificing resolution. For VREF = 5 V, this yields a usable input span of 0.5 V to 4.5 V - providing ample headroom for amplifier output swing while maintaining 16-bit code integrity in the LTC2380IMS-16#PBF.

What package type is used for the LTC2380IMS-16#PBF?

The LTC2380IMS-16#PBF uses a 16-lead plastic MSOP package (4.0 mm × 3.0 mm × 1.1 mm), rated for operation from –40°C to +85°C. Unlike the DFN variant (e.g., LTC2380IDE-16#PBF), the MSOP version has no exposed thermal pad. It is RoHS-compliant and features lead-free finish (#PBF), with pin 1 marked by a dot and pin 17 omitted (DFN-only).

Can the LTC2380IMS-16#PBF interface directly with a 1.8 V microcontroller?

Yes, the LTC2380IMS-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, all digital I/O pins (SCK, SDO, RDL/SDI, CNV, BUSY, CHAIN) operate at 1.8 V logic thresholds - enabling direct connection to 1.8 V FPGAs or microcontrollers without level shifters. The LTC2380IMS-16#PBF maintains full timing specifications (e.g., 100 MHz SCK max) across the entire OVDD range.
