Analog Devices Inc. LTC2310CMSE-14#TRPBF

Overview

LTC2310CMSE-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, 82 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, making it suitable for high-dynamic-range data acquisition in industrial and communications systems.

For engineers reviewing the LTC2310CMSE-14#TRPBF datasheet, LTC2310CMSE-14#TRPBF pinout, LTC2310CMSE-14#TRPBF application, or LTC2310CMSE-14#TRPBF equivalent, key selection considerations include guaranteed no-missing-codes operation at 14 bits, CMOS/LVDS SPI-compatible serial interface configurability, –40°C to 70°C operating temperature range (C-grade), 16-lead MSOP package, and support for nap/sleep power modes.

Technical Context

The LTC2310CMSE-14#TRPBF implements a 15-bit SAR architecture with differential sampling switch and on-chip CDAC, achieving zero-cycle latency and full 2 Msps throughput without pipeline delay. Its analog front-end supports bipolar, unipolar, and pseudo-differential signal configurations without external configuration.

It features dual-reference capability: an internal 4.096 V (±20 ppm/°C max) buffered reference with REFIN 1.25 V output, and external reference input via REFIN/REFOUT pins. Digital I/O supports selectable CMOS or LVDS signaling via the CMOS/LVDS pin, with independent OVDD (1.71–2.5 V) supply for interface logic.

FAQ

What is the operating temperature range for the LTC2310CMSE-14#TRPBF?

The LTC2310CMSE-14#TRPBF is rated for 0°C to 70°C (Commercial grade). This is confirmed by the "C" suffix in the part number and the order information table listing "LTC2310CMSE-14#PBF" and "LTC2310CMSE-14#TRPBF" under the 0°C to 70°C temperature range. It is distinct from the I-grade (–40°C to 85°C) and H-grade (–40°C to 125°C) variants.

Does the LTC2310CMSE-14#TRPBF require an external reference?

No, the LTC2310CMSE-14#TRPBF includes an onboard low-drift 4.096 V temperature-compensated reference buffer. It also provides a 1.25 V buffered REFIN output and accepts external references via the REFIN pin-offering flexibility without mandating external components. The internal reference is fully functional out-of-the-box for most applications.

How does the CMOS/LVDS pin (Pin 10) configure the serial interface of the LTC2310CMSE-14#TRPBF?

The CMOS/LVDS pin (Pin 10) selects the digital interface mode: grounding enables CMOS I/O (single-ended SDO+/SCK+), tying to OVDD enables standard LVDS (differential SDO+/SDO–, SCK+/SCK–), and leaving it floating enables low-power LVDS mode. This pin directly controls receiver configuration and power state-no register writes or timing sequences are needed.

What is the significance of "no cycle latency" in the LTC2310CMSE-14#TRPBF specification?

"No cycle latency" means the LTC2310CMSE-14#TRPBF delivers the conversion result for a given CNV pulse immediately after the conversion completes-without pipelining delay. Unlike sigma-delta or pipeline ADCs, there is no fixed number of clock cycles between trigger and valid output, enabling deterministic timing for real-time control loops and burst-mode acquisition.

Can the LTC2310CMSE-14#TRPBF digitize single-ended signals?

Yes, the LTC2310CMSE-14#TRPBF supports pseudo-differential single-ended operation: connect the reference (e.g., ground or mid-supply) to AIN– and the signal to AIN+, leveraging its wide 0 V to VDD common mode range and high CMRR. No hardware reconfiguration or software setup is required-the same pinout and timing apply.
