Analog Devices Inc. LTC2310IMSE-12#TRPBF

Overview

LTC2310IMSE-12#TRPBF 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 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 sensing and optical networking.

For engineers reviewing the LTC2310IMSE-12#TRPBF datasheet, LTC2310IMSE-12#TRPBF pinout, LTC2310IMSE-12#TRPBF application, or LTC2310IMSE-12#TRPBF equivalent, key selection criteria include guaranteed no-missing-codes performance, CMOS/LVDS serial interface configurability, –40°C to 85°C temperature grade, 16-lead MSOP package, and support for nap/sleep power modes.

Technical Context

The LTC2310IMSE-12#TRPBF implements a 13-bit SAR architecture with differential sampling switch network (15 Ω R_ON, 10 pF C_IN) and on-chip 4.096 V temperature-compensated reference (20 ppm/°C max drift). Its timing logic initiates conversion on CNV falling edge, completes conversion in 220 ns, and outputs 13-bit two's complement data MSB-first on SCK falling edges with zero cycle latency.

It supports dual I/O modes: CMOS (OVDD = 1.8 V or 2.5 V) with single-ended SDO+/SCK+, or LVDS (OVDD = 2.5 V) with differential SDO±/SCK± terminated by 100 Ω. The REFOUT buffer may be disabled via REFIN = GND to accept external 1.25 V reference, enabling flexible system-level voltage scaling.

FAQ

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

The LTC2310IMSE-12#TRPBF is specified for operation from –40°C to +85°C, matching the "I" grade designation in the LTC2310 family. This range is validated across all electrical parameters including INL, SNR, and reference accuracy, making it suitable for industrial and automotive under-hood applications where ambient temperatures exceed commercial-grade limits.

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

No, the LTC2310IMSE-12#TRPBF includes an onboard low-drift 4.096 V temperature-compensated reference (20 ppm/°C max). However, it also provides a 1.25 V buffered REFIN pin that can disable the internal REFOUT buffer, allowing an external reference to drive REFOUT - giving designers flexibility for system-level reference sharing or improved accuracy.

How does the CMOS/LVDS pin (Pin 10) configure the serial interface on the LTC2310IMSE-12#TRPBF?

Pin 10 (CMOS/LVDS) selects the physical layer: grounded for CMOS mode (single-ended SDO+/SCK+), tied to OVDD for LVDS mode (differential SDO±/SCK±), or left floating for low-power LVDS mode. This hardware-selectable configuration avoids firmware changes and supports migration between noise-sensitive and power-constrained environments using the same PCB layout.

What is the significance of "no cycle latency" in the LTC2310IMSE-12#TRPBF timing specification?

"No cycle latency" means the conversion result for a given CNV trigger is available for readout immediately after the conversion completes - there is no pipeline delay or additional sample cycles before data appears on SDO. For the LTC2310IMSE-12#TRPBF, this enables deterministic real-time processing in FPGA-based systems where timing predictability is essential for closed-loop control and waveform generation.

Can the LTC2310IMSE-12#TRPBF digitize single-ended signals without external circuitry?

Yes, the LTC2310IMSE-12#TRPBF supports pseudo-differential single-ended operation: connect the signal to AIN+ and a clean reference (e.g., ground or mid-rail) to AIN–. Its wide 0 V to VDD common mode range and 85 dB CMRR at 500 kHz allow effective common-mode noise rejection without external amplifiers - simplifying front-end design for sensor interfaces and legacy analog systems.
