Analog Devices Inc. LTC2310IMSE-16#PBF

Overview

LTC2310IMSE-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 2 Msps successive approximation register (SAR) analog-to-digital converter with differential inputs, ±3 LSB typical INL, 82 dB SNR 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, integrates a low-drift 4.096 V internal reference, and supports CMOS or LVDS serial interface-ideal for high-speed data acquisition in optical networking and motor control.

For engineers reviewing the LTC2310IMSE-16#PBF datasheet, LTC2310IMSE-16#PBF pinout, LTC2310IMSE-16#PBF application, or LTC2310IMSE-16#PBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation, –40°C to +85°C industrial temperature grade, 2 Msps throughput with zero cycle latency, and dual-mode (CMOS/LVDS) I/O compatibility for FPGA or ASIC interfacing.

Technical Context

The LTC2310IMSE-16#PBF implements a true differential SAR architecture with a 100 MHz –3 dB input bandwidth and 1 ps RMS aperture jitter, enabling accurate digitization of fast transient signals. Its internal 4.096 V reference exhibits ≤20 ppm/°C drift and supports external 1.25 V reference injection via REFIN.

Conversion is initiated by a TTL-compatible CNV pulse; output data is clocked MSB-first on SCK falling edges with configurable CMOS (1.8 V–2.5 V OVDD) or LVDS (100 Ω terminated) signaling. The device features nap and sleep modes, achieving 0.5 µW sleep current at 5 V.

FAQ

What is the operating temperature range for the LTC2310IMSE-16#PBF?

The LTC2310IMSE-16#PBF is rated for industrial operation from –40°C to +85°C. All key specifications-including INL (±8 LSB guaranteed), SNR (75.5 dB min), and reference drift (≤20 ppm/°C)-are validated across this full range. This distinguishes it from the commercial-grade C version (0°C to 70°C) and high-temp H version (–40°C to 125°C).

Does the LTC2310IMSE-16#PBF require an external reference?

No, the LTC2310IMSE-16#PBF includes an onboard 4.096 V temperature-compensated reference with ≤20 ppm/°C drift. An external 1.25 V reference may be applied via REFIN to override the internal reference, but it is not required. The device also provides a buffered 1.25 V output on REFIN for auxiliary use.

How does the CMOS/LVDS pin (Pin 10) configure the serial interface?

The CMOS/LVDS pin (Pin 10) selects the physical layer: grounded for CMOS mode (single-ended SDO+/SCK+), tied to OVDD for standard LVDS mode (differential SDO+/SDO–, SCK+/SCK–), or left floating for low-power LVDS mode. Configuration must be set before power-up and remains static during operation.

What is the significance of "no cycle latency" in the LTC2310IMSE-16#PBF?

"No cycle latency" means the conversion result for sample N is fully available at the serial output immediately after the conversion time (t_CONV ≈ 220 ns), with no additional pipeline stages. This enables deterministic, real-time sampling crucial for closed-loop control systems like motor drives, where output timing directly impacts stability and response.

Can the LTC2310IMSE-16#PBF interface directly with a 1.8 V FPGA I/O bank?

Yes. The LTC2310IMSE-16#PBF supports 1.8 V OVDD operation in CMOS mode. With OVDD = 1.8 V, its digital inputs (CNV, SCK) accept 0.2 × OVDD to 0.8 × OVDD logic thresholds, and SDO+ outputs swing rail-to-rail between GND and 1.8 V - enabling seamless, level-compatible interfacing with 1.8 V FPGA I/O banks without translators.
