Analog Devices Inc. LTC2310CMSE-16#TRPBF

Overview

LTC2310CMSE-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 2 Msps successive approximation register (SAR) analog-to-digital converter with differential inputs, ±3 LSB typical INL, 82 dB SNR at 500 kHz, and wide 0 V to VDD common mode input range. It operates from a single 3.3 V or 5 V supply, integrates a low-drift 4.096 V internal reference, and supports CMOS or LVDS serial interface - ideal for high-speed data acquisition in industrial instrumentation and optical networking.

For engineers reviewing the LTC2310CMSE-16#TRPBF datasheet, LTC2310CMSE-16#TRPBF pinout, LTC2310CMSE-16#TRPBF application, or LTC2310CMSE-16#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes performance, 2 Msps throughput with zero cycle latency, differential input flexibility across unipolar/bipolar/pseudo-differential configurations, and operation over 0°C to 70°C in a 16-lead MSOP package.

Technical Context

The LTC2310CMSE-16#TRPBF implements a true differential SAR architecture with integrated sample-and-hold, supporting full-scale input ranges of ±4.096 V (differential) and common mode voltages from 0 V to VDD. Its internal 4.096 V reference exhibits ≤20 ppm/°C drift and can be disabled to accept an external 1.25 V buffered reference via REFIN.

It features dual-mode digital I/O: CMOS mode (OVDD = 1.8 V or 2.5 V) or LVDS mode (OVDD = 2.5 V, 100 Ω differential termination), with configurable SDO/SCK pins and a dedicated CMOS/LVDS mode-select pin. Conversion is initiated by a TTL-compatible CNV pulse, and output data is clocked MSB-first on SCK falling edges with no pipeline delay.

FAQ

What is the maximum sampling rate supported by the LTC2310CMSE-16#TRPBF?

The LTC2310CMSE-16#TRPBF supports a maximum sampling rate of 2 Msps, with guaranteed timing parameters including t_CYC = 500 ns minimum and no cycle latency. This allows deterministic, real-time acquisition of signals up to 1 MHz bandwidth while maintaining full 16-bit resolution and no missing codes across its 0°C to 70°C operating range.

Does the LTC2310CMSE-16#TRPBF require an external reference voltage?

No, the LTC2310CMSE-16#TRPBF includes an onboard low-drift 4.096 V temperature-compensated reference buffer. However, it also provides a 1.25 V buffered REFIN pin that can disable the internal REFOUT buffer, enabling use of an external reference - offering design flexibility for system-level voltage referencing or improved absolute accuracy.

Can the LTC2310CMSE-16#TRPBF interface directly with an FPGA using LVDS signaling?

Yes, the LTC2310CMSE-16#TRPBF supports LVDS mode via the CMOS/LVDS pin (Pin 10). When tied to OVDD, it configures SDO+/SDO– and SCK+/SCK– for differential LVDS operation with 100 Ω termination, compatible with standard FPGA LVDS I/O banks operating at 2.5 V - enabling noise-immune, high-speed serial data transfer up to 64 MHz SCK frequency.

What is the differential input voltage range of the LTC2310CMSE-16#TRPBF?

The LTC2310CMSE-16#TRPBF has a differential input voltage range of ±REFOUT, which is ±4.096 V when using the internal reference - yielding an 8 V_P-P full-scale range. The common mode input range spans 0 V to VDD, allowing flexible signal conditioning topologies including pseudo-differential unipolar, bipolar, and fully differential configurations without external level shifting.

How does the LTC2310CMSE-16#TRPBF manage power in low-duty-cycle applications?

The LTC2310CMSE-16#TRPBF offers nap and sleep modes to reduce power during idle periods: nap mode draws 14 mW (V_DD = 5 V), while sleep mode consumes only 0.5 µW. These states are entered via control of the CNV signal and internal timing logic, enabling significant energy savings in burst-mode data acquisition systems without sacrificing wake-up speed or conversion accuracy upon reactivation.
