Analog Devices Inc. LTC1407ACMSE#TRPBF

Overview

LTC1407ACMSE#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit, 3Msps simultaneous-sampling dual-channel ADC with two fully differential 1.5Msps per-channel throughput, 80dB CMRR at 100kHz, 0V–2.5V unipolar input range, and 10μW Sleep shutdown mode - designed for high-speed portable data acquisition and I/Q demodulation.

For engineers reviewing the LTC1407ACMSE#TRPBF datasheet, LTC1407ACMSE#TRPBF pinout, LTC1407ACMSE#TRPBF application, or LTC1407ACMSE#TRPBF equivalent, key selection considerations include simultaneous sampling integrity, 14-bit resolution with ±0.5 LSB integral linearity, MSOP-10 package thermal performance, and compatibility with 3V single-supply systems requiring low-power high-fidelity analog capture.

Technical Context

The LTC1407ACMSE#TRPBF integrates two independent sample-and-hold circuits triggered synchronously on the rising edge of CONV, enabling true simultaneous sampling across CH0 and CH1. Each channel converts at 1.5Msps using a successive-approximation architecture referenced to an internal 2.5V bandgap.

Its 3-wire serial interface outputs 32 clocks per conversion cycle (14 bits × 2 channels), with SDO three-state control and precise timing alignment (aperture skew ≤200ps). The device supports external reference overdrive (2.55V–VDD) and maintains full linear bandwidth up to 5MHz with SINAD ≥70.5dB at 100kHz.

FAQ

What is the resolution and sampling rate of the LTC1407ACMSE#TRPBF?

The LTC1407ACMSE#TRPBF is a 14-bit ADC with simultaneous sampling capability at 3Msps aggregate (1.5Msps per channel). Its 14-bit resolution provides 16384 discrete output levels, and the simultaneous sampling architecture ensures time-aligned capture across both differential input channels - critical for phase-sensitive applications like I/Q demodulation and motor current sensing. The LTC1407ACMSE#TRPBF achieves this while drawing only 4.7mA from a 3V supply.

Does the LTC1407ACMSE#TRPBF include an internal voltage reference?

Yes, the LTC1407ACMSE#TRPBF integrates a factory-trimmed 2.5V bandgap reference (Pin 3, VREF) with 15ppm/°C tempco and 600μV/V line regulation. This internal reference establishes the 0V–2.5V unipolar input span and can be overdriven by an external reference between 2.55V and VDD for improved accuracy or system-level reference sharing. The LTC1407ACMSE#TRPBF requires a 10μF bypass capacitor on VREF for optimal noise performance.

How does the LTC1407ACMSE#TRPBF achieve simultaneous sampling across two channels?

The LTC1407ACMSE#TRPBF uses two independent sample-and-hold circuits triggered synchronously on the rising edge of the CONV signal, ensuring true simultaneous capture of CH0± and CH1± inputs. Aperture skew between channels is guaranteed ≤200ps, and both channels share identical acquisition timing (t_ACQ = 39ns). This architecture enables coherent dual-channel measurements without inter-channel timing artifacts - a core requirement for the LTC1407ACMSE#TRPBF in multiphase control and communications applications.

What power-saving modes does the LTC1407ACMSE#TRPBF support?

The LTC1407ACMSE#TRPBF offers two low-power states: Nap mode (1.1mA, 3mW) and Sleep mode (2μA, 10μW), entered via specific pulse sequences on the CONV pin. In Sleep mode, the internal reference and logic are powered down, reducing supply current to microamp levels while retaining fast wake-up capability (<2ms VREF settling). These modes make the LTC1407ACMSE#TRPBF suitable for battery-powered DAQ systems requiring intermittent high-speed capture.

What package type and thermal characteristics apply to the LTC1407ACMSE#TRPBF?

The LTC1407ACMSE#TRPBF is housed in a 10-lead MSOP (MSE) package measuring 3mm × 3mm with an exposed thermal pad. Its thermal resistance is θ_JA = 40°C/W, and maximum junction temperature is 150°C. The exposed pad must be soldered directly to the PCB ground plane for effective heat dissipation and low-noise analog performance - a critical layout requirement explicitly specified for reliable operation of the LTC1407ACMSE#TRPBF.
