Analog Devices Inc. LTC2310CMSE-12#TRPBF

Overview

LTC2310CMSE-12#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs, 2 Msps throughput, ±1 LSB INL guaranteed, 73 dB SNR typical 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 and integrates a low-drift 4.096 V internal reference - ideal for high-speed data acquisition in industrial sensing and optical networking.

For engineers reviewing the LTC2310CMSE-12#TRPBF datasheet, LTC2310CMSE-12#TRPBF pinout, LTC2310CMSE-12#TRPBF application, or LTC2310CMSE-12#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes operation, CMOS/LVDS configurable serial interface, nap/sleep power modes, –40°C to 125°C H-grade thermal rating, and MSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The LTC2310CMSE-12#TRPBF implements a 13-bit SAR architecture with differential sampling switch and on-chip CDAC, achieving zero-cycle latency and deterministic 220 ns conversion time. Its analog front-end supports bipolar/unipolar pseudo-differential and fully differential input configurations without external configuration.

It features dual-reference capability: internally buffered 4.096 V (±20 ppm/°C max) or externally driven 1.25 V reference input, with REFIN/REFOUT pins enabling flexible reference sourcing. Digital I/O supports CMOS (1.8 V–2.5 V OVDD) or LVDS (100 Ω terminated) modes selected via the CMOS/LVDS pin.

FAQ

What is the operating temperature range for the LTC2310CMSE-12#TRPBF?

The LTC2310CMSE-12#TRPBF is the C-grade variant, specified for 0°C to 70°C ambient operation. This differs from the I-grade (–40°C to 85°C) and H-grade (–40°C to 125°C) versions. The part marking "C" in LTC2310CMSE-12#TRPBF explicitly denotes the commercial temperature range, validated per Absolute Maximum Ratings and Electrical Characteristics tables in the official datasheet.

Does the LTC2310CMSE-12#TRPBF require an external reference?

No, the LTC2310CMSE-12#TRPBF includes an onboard 4.096 V temperature-compensated reference with ≤20 ppm/°C drift. It also provides a 1.25 V buffered REFIN pin that can be grounded to disable the internal REFOUT buffer - enabling use of an external reference if higher accuracy or different voltage is needed. The device functions fully with only the internal reference.

How does the CMOS/LVDS pin (Pin 10) affect interface operation of the LTC2310CMSE-12#TRPBF?

The CMOS/LVDS pin (Pin 10) configures the digital interface: tied to GND selects CMOS mode (single-ended SDO+/SCK+), tied to OVDD selects standard LVDS mode (differential SDO±/SCK±), and left floating enables low-power LVDS mode. This pin determines driver strength, termination requirements, and power consumption - all verified in the Digital Inputs and Outputs section of the datasheet.

Can the LTC2310CMSE-12#TRPBF interface directly with a 1.8 V FPGA I/O bank?

Yes - when configured in CMOS mode (CMOS/LVDS pin = GND), the LTC2310CMSE-12#TRPBF supports OVDD = 1.71 V to 2.5 V, including 1.8 V. Its VIH/VIL thresholds scale with OVDD (0.8× and 0.2× OVDD), and SDO/SCK logic levels are referenced to OVDD. This allows direct, level-compatible connection to 1.8 V FPGA banks without translators.

What power savings does the nap mode provide for the LTC2310CMSE-12#TRPBF?

In nap mode, the LTC2310CMSE-12#TRPBF reduces IVDD from 10 mA (active, 2 Msps) to 2.8–4 mA - cutting analog supply current by ~60%. This state retains reference and bias settings, allowing sub-microsecond wake-up to full operation. Nap mode is activated automatically after conversion completion and is documented in the Power Requirements table with test conditions at VDD = 3.3 V and 5 V.
