Analog Devices Inc. LTC2310HMSE-14#TRPBF

Overview

LTC2310HMSE-14#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs, 2 Msps throughput, ±2.5 LSB INL guaranteed over –40°C to 125°C, and integrated 4.096 V temperature-compensated reference. It operates from single 3.3 V or 5 V supply, delivers 82 dB SNR at 500 kHz input, and targets high-speed data acquisition in harsh environments.

For engineers reviewing the LTC2310HMSE-14#TRPBF datasheet, LTC2310HMSE-14#TRPBF pinout, LTC2310HMSE-14#TRPBF application, or LTC2310HMSE-14#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes operation at full 14-bit resolution, wide common-mode input range (0 V to VDD), LVDS/CMOS configurable serial interface, low-power nap/sleep modes, and automotive-grade temperature rating.

Technical Context

The LTC2310HMSE-14#TRPBF implements a 15-bit SAR architecture with internal sample-and-hold, supporting true differential acquisition without external configuration. Its input stage accepts 8 V_P-P differential signals with common-mode range spanning 0 V to VDD, enabling direct interfacing with sensor front-ends and isolated amplifiers.

It integrates dual reference paths: a factory-trimmed 4.096 V (±20 ppm/°C max) internal reference with buffered REFIN (1.25 V) input, and supports external reference injection via REFIN grounding. Serial output is SPI-compatible with selectable CMOS or LVDS I/O using the CMOS/LVDS pin, and features zero-cycle latency for deterministic timing in real-time control loops.

FAQ

What is the guaranteed integral nonlinearity (INL) specification for the LTC2310HMSE-14#TRPBF across its full operating temperature range?

The LTC2310HMSE-14#TRPBF guarantees ±2.5 LSB INL over its entire –40°C to +125°C operating temperature range. This specification is tested and assured per the device's Absolute Maximum Ratings and Electrical Characteristics tables, ensuring monotonic behavior and accurate end-point linearity without calibration in automotive and industrial deployments.

Does the LTC2310HMSE-14#TRPBF support both CMOS and LVDS serial interfaces, and how is the mode selected?

Yes, the LTC2310HMSE-14#TRPBF supports both CMOS and LVDS serial interfaces. Mode selection is controlled by the CMOS/LVDS pin (Pin 10): grounding selects CMOS mode, tying to OVDD selects standard LVDS mode, and leaving it floating enables low-power LVDS mode. This allows flexible integration with FPGAs, DSPs, or microcontrollers using either signaling standard.

What reference voltage options does the LTC2310HMSE-14#TRPBF provide, and can an external reference be used?

The LTC2310HMSE-14#TRPBF provides an internal 4.096 V temperature-compensated reference (REFOUT) with ≤20 ppm/°C drift. It also offers a buffered 1.25 V reference output (REFIN) that can be grounded to disable the internal REFOUT buffer, allowing an external reference (1.25 V to VDD) to drive REFOUT directly - enabling custom full-scale ranges.

What power-saving modes does the LTC2310HMSE-14#TRPBF offer, and what are their typical current draws at 5 V supply?

The LTC2310HMSE-14#TRPBF offers Nap and Sleep modes. At 5 V supply, Nap mode draws 2.8–4 mA (IVDD), reducing active power during idle cycles; Sleep mode draws 0.5–40 µA (IVDD + IOVDD), ideal for battery-backed data loggers. Both modes retain register state and resume conversion within microseconds upon wake-up.

Is the LTC2310HMSE-14#TRPBF pin-compatible with other members of the LTC2310 family, such as the LTC2310CMSE-14#TRPBF?

Yes, the LTC2310HMSE-14#TRPBF is pin-compatible with all variants in the LTC2310-14 family (C-, I-, and H-grade), sharing identical 16-lead MSOP packaging, pinout, and electrical interface. The only differences are temperature rating (–40°C to +125°C for H-grade) and screening - enabling drop-in replacement in existing designs requiring extended thermal performance.
