Analog Devices Inc. LTC2310HMSE-12#PBF

Overview

LTC2310HMSE-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 over –40°C to 125°C, and integrated 4.096 V temperature-compensated reference. It operates from a single 3.3 V or 5 V supply, delivers 73 dB SNR at 500 kHz input, and supports CMOS or LVDS serial interface - ideal for high-speed industrial data acquisition and motor control systems.

For engineers reviewing the LTC2310HMSE-12#PBF datasheet, LTC2310HMSE-12#PBF pinout, LTC2310HMSE-12#PBF application, or LTC2310HMSE-12#PBF equivalent, key selection criteria include guaranteed operation across –40°C to 125°C, no missing codes at 12 bits, differential input common mode range of 0 V to VDD, low-power nap/sleep modes, and dual-mode (CMOS/LVDS) SPI-compatible serial I/O compatibility with FPGA or DSP host interfaces.

Technical Context

The LTC2310HMSE-12#PBF implements a 13-bit SAR architecture with differential sampling switch and on-chip CDAC, achieving zero-cycle latency and full 2 Msps throughput without pipeline delay. Its internal 4.096 V reference exhibits ≤20 ppm/°C drift and supports external 1.25 V buffered reference input via REFIN pin.

It features dual digital I/O modes: CMOS (1.8 V–2.5 V OVDD) and LVDS (2.5 V OVDD), with configurable SDO/SCK pin assignments and dedicated CMOS/LVDS mode select pin. Input stage includes 10 pF analog input capacitance and 15 Ω switch R_ON, enabling robust pseudo-differential and fully differential signal acquisition without external configuration.

FAQ

What is the guaranteed operating temperature range for the LTC2310HMSE-12#PBF?

The LTC2310HMSE-12#PBF is rated for continuous operation from –40°C to +125°C, verified per the H-grade specification in the official datasheet. This extended range is confirmed by thermal characterization and burn-in testing, making it suitable for under-hood automotive and industrial edge computing deployments where ambient temperatures exceed standard commercial or industrial grades.

Does the LTC2310HMSE-12#PBF require an external reference, or does it include one?

The LTC2310HMSE-12#PBF includes an onboard 4.096 V temperature-compensated reference with ≤20 ppm/°C drift, eliminating the need for an external reference in most applications. It also provides a 1.25 V buffered REFIN pin that can disable the internal REFOUT buffer - allowing use of an external reference if tighter initial accuracy or different voltage is required.

Can the LTC2310HMSE-12#PBF interface directly with a 1.8 V FPGA I/O bank?

Yes - the LTC2310HMSE-12#PBF supports 1.8 V OVDD operation in CMOS mode. When Pin 10 (CMOS/LVDS) is grounded and OVDD is set to 1.8 V, all digital outputs (SDO+, SCK+) operate at 1.8 V logic levels with VIH ≥ 1.44 V and VIL ≤ 0.36 V, ensuring reliable communication with 1.8 V FPGA I/O banks without level shifters.

How does the LTC2310HMSE-12#PBF achieve zero-cycle latency, and why does it matter?

The LTC2310HMSE-12#PBF uses a true successive approximation architecture with no pipeline stages, so the conversion result for a given CNV pulse is available immediately after t_CONV (220 ns typ) - with no additional clock cycles needed. This zero-cycle latency is essential for real-time control loops (e.g., motor current regulation) where deterministic timing avoids phase lag and instability.

What package type and thermal characteristics does the LTC2310HMSE-12#PBF use?

The LTC2310HMSE-12#PBF uses a 16-lead plastic MSOP (4 mm × 5 mm) with exposed thermal pad (Pin 17). Its θ_JA is 40°C/W when the exposed pad is soldered to a 2-layer PCB ground plane, enabling reliable operation at full 2 Msps throughput even at +125°C ambient - critical for compact, fanless industrial enclosures.
