Analog Devices Inc. LTC2310IMSE-12#PBF

Overview

LTC2310IMSE-12#PBF 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 motor control and optical networking systems.

For engineers reviewing the LTC2310IMSE-12#PBF datasheet, LTC2310IMSE-12#PBF pinout, LTC2310IMSE-12#PBF application, or LTC2310IMSE-12#PBF equivalent, key selection criteria include guaranteed no-missing-codes operation over –40°C to +85°C, CMOS/LVDS SPI-compatible serial interface configurability, differential input voltage range of ±4.096 V, and power dissipation of 35 mW at 5 V - all within a compact 16-lead MSOP package.

Technical Context

The LTC2310IMSE-12#PBF implements a 13-bit SAR architecture with 2's complement output coding, achieving zero-cycle latency and full 12-bit resolution without missing codes across its operating temperature range. Its differential sampling switch network features 10 pF input capacitance and ~15 Ω on-resistance, enabling robust acquisition of bipolar, unipolar, and pseudo-differential signals without external configuration.

Internal timing is synchronized to the CNV falling edge, initiating conversion followed by immediate readout via SCK-driven serial transfer. The device supports dual I/O modes: CMOS (single-ended SDO+/SCK+) or LVDS (differential SDO±/SCK±), with OVDD configurable from 1.71 V to 2.5 V - allowing seamless interfacing with FPGAs, DSPs, or microcontrollers operating at 1.8 V or 2.5 V logic levels.

FAQ

What is the operating temperature range for the LTC2310IMSE-12#PBF?

The LTC2310IMSE-12#PBF is rated for operation from –40°C to +85°C, meeting industrial-grade reliability requirements. This is confirmed in the Absolute Maximum Ratings table and Order Information section of the official datasheet, where "I" grade denotes the –40°C to +85°C range. The device maintains ±1 LSB INL and full 12-bit no-missing-codes performance across this entire span.

Does the LTC2310IMSE-12#PBF require an external reference?

No, the LTC2310IMSE-12#PBF includes an onboard low-drift 4.096 V temperature-compensated reference with 20 ppm/°C max drift. An external reference is optional and only needed when higher accuracy or different voltage levels are required - injected via the REFIN pin, which disables the internal REFOUT buffer when grounded.

Can the LTC2310IMSE-12#PBF interface with a 1.8 V FPGA?

Yes, the LTC2310IMSE-12#PBF supports 1.8 V I/O operation via its OVDD supply (1.71 V to 2.5 V range). When configured in CMOS mode (CMOS/LVDS pin grounded), SDO and SCK operate at OVDD levels - enabling direct, level-compatible connection to 1.8 V FPGA I/O banks without translators.

How does the CNV pin function in the LTC2310IMSE-12#PBF?

The CNV pin is a TTL-compatible convert trigger: a falling edge initiates sampling and conversion, and the resulting 13-bit 2's complement code becomes available for readout on the next SCK edges. There is zero cycle latency - meaning data is ready immediately after conversion completes, enabling deterministic timing in real-time control systems using the LTC2310IMSE-12#PBF.

What power-saving modes does the LTC2310IMSE-12#PBF support?

The LTC2310IMSE-12#PBF offers Nap Mode (2.8 mA typical at 5 V) and Sleep Mode (0.1 µA typical at 3.3 V), both entered via control of the CNV pin timing sequence. These modes reduce power during idle periods while preserving fast wake-up - critical for battery-operated or thermally constrained applications using the LTC2310IMSE-12#PBF.
