Product details
Overview
LTC1407ACMSE-1#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit, 3Msps simultaneous-sampling dual-channel ADC with differential inputs, 80dB CMRR at 100kHz, ±1.25V differential input range, and 10μW sleep shutdown mode. It operates from a single 3V supply in a 10-lead MSOP package and targets high-speed portable data acquisition systems requiring precise I/Q demodulation or multiphase motor current sensing.
For engineers reviewing the LTC1407ACMSE-1#TRPBF datasheet, LTC1407ACMSE-1#TRPBF pinout, LTC1407ACMSE-1#TRPBF application, or LTC1407ACMSE-1#TRPBF equivalent, key selection criteria include simultaneous sampling skew (200ps), 14-bit resolution with ±0.5LSB integral linearity, 72.0dB SINAD at 100kHz, internal 2.5V reference with 15ppm/°C tempco, and MSOP-10 thermal performance (θJA = 40°C/W).
Technical Context
The LTC1407ACMSE-1#TRPBF integrates two independent sample-and-hold circuits sampled simultaneously on the rising edge of CONV, followed by sequential 14-bit conversion at 1.5Msps per channel. Its architecture supports true differential signal acquisition with 13pF input capacitance and 39ns acquisition time.
It uses an internal 2.5V bandgap reference (15ppm/°C tempco, 2ms wake-up settling) and outputs 32-bit serial data via a 3-wire SDO/SCK/CONV interface. The device achieves 73.5dB SINAD and –90dB THD at 100kHz with external 3.3V reference, and maintains 80dB common-mode rejection up to 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - enables 152μV LSB quantization for precision sensor or instrumentation applications. |
| Sampling Rate | 3Msps aggregate (1.5Msps per channel) - supports Nyquist-limited bandwidth up to 750kHz per channel. |
| Differential Input Range | ±1.25V - allows direct AC-coupled signal acquisition without external level-shifting in single-supply 3V systems. |
| Common-Mode Rejection | 80dB at 100kHz - eliminates ground-loop noise and enables robust measurement in electrically noisy industrial environments. |
| Power Consumption | 4.7mA active (14mW), 2.0μA nap mode, 10μW sleep mode - extends battery life in portable test equipment and handheld meters. |
| Aperture Skew | 200ps between CH0 and CH1 - ensures sub-degree phase alignment critical for I/Q demodulation and vector control. |
| SINAD | 72.0dB at 100kHz (internal VREF), 73.5dB with 3.3V external VREF - delivers >11.6 ENOB for high-fidelity signal reconstruction. |
Pinout & Package
Package: 10-lead plastic MSOP (MSE), exposed pad (Pin 11) soldered to PCB ground plane; θJA = 40°C/W, TJMAX = 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0+ (Pin 1) | Noninverting input, Channel 0 | Differential pair with CH0–; accepts 0–3V absolute voltage while maintaining ±1.25V differential swing. |
| CH0– (Pin 2) | Inverting input, Channel 0 | Full differential complement to CH0+; common-mode range 0–VDD enables single-supply operation. |
| VREF (Pin 3) | Internal 2.5V reference output | Bypassed with 10μF + 0.1μF capacitors; overdrivable with 2.55V–VDD external reference for improved accuracy. |
| CH1+ (Pin 4) | Noninverting input, Channel 1 | Simultaneously sampled with CH0+; identical electrical specs enable matched dual-channel acquisition. |
| CH1– (Pin 5) | Inverting input, Channel 1 | Paired with CH1+; 200ps aperture skew vs CH0± ensures time-aligned sampling for phase-sensitive applications. |
| GND (Pins 6, 11) | Analog/digital ground & exposed pad | Single low-impedance return path for analog signals and digital outputs; exposed pad must be soldered for thermal and noise integrity. |
| VDD (Pin 7) | 3V supply input | Powers entire IC; requires 10μF + 0.1μF local bypassing close to Pins 6/7 to suppress switching noise. |
| SDO (Pin 8) | 3-state serial data output | Outputs 14-bit 2's complement words for both channels in 32-clock frame; Hi-Z when SCK inactive. |
| SCK (Pin 9) | Serial clock input | Edge-triggered timing source; rising edge advances conversion state machine and clocks out data. |
| CONV (Pin 10) | Convert start / mode control | Rising edge initiates simultaneous sampling; multiple pulses enter nap (2 pulses) or sleep (4+ pulses) modes. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous sampling | Guaranteed 200ps inter-channel aperture skew enables coherent dual-channel measurements for vector control and I/Q processing. |
| Low-power shutdown modes | 10μW sleep and 3mW nap modes reduce system power budget without compromising wake-up latency (2ms VREF settling). |
| Differential input architecture | 80dB CMRR at 100kHz rejects noise from shared ground paths-critical in motor drives and telecom baseband stages. |
| Integrated 2.5V reference | 15ppm/°C tempco and 600μV/V line regulation ensure stable full-scale span across temperature and supply variation. |
| MSOP-10 thermal design | Exposed pad and 40°C/W θJA allow sustained 3Msps operation in compact portable enclosures without forced air cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8327IPW | 16-bit, 500kSPS, SPI interface, no internal reference, 16-pin TSSOP | Lower throughput but higher resolution; requires external reference and separate power domains | Prefer for DC-precision applications where 16-bit static accuracy outweighs speed and integration needs |
| AD7357BRUZ | 14-bit, 4.2Msps, parallel interface, 24-pin TSSOP, 3.3V-only supply | Higher speed and parallel output but larger footprint and no sleep mode; lacks integrated reference | Choose when system demands maximum throughput and has space for 24-pin package and parallel bus routing |

FAQ
What is the guaranteed resolution and linearity of the LTC1407ACMSE-1#TRPBF?
The LTC1407ACMSE-1#TRPBF guarantees 14-bit resolution with no missing codes and ±0.5LSB typical integral linearity error over the full 0°C to 70°C operating range. This corresponds to ±76μV absolute error at the ±1.25V differential input range, enabling high-accuracy measurement in instrumentation-grade applications.
How does the LTC1407ACMSE-1#TRPBF achieve simultaneous sampling across two channels?
The LTC1407ACMSE-1#TRPBF uses two independent sample-and-hold circuits triggered by the same rising edge of the CONV signal, ensuring simultaneous capture of CH0+/- and CH1+/- inputs. Aperture skew is tightly controlled at 200ps max, preserving phase coherence required for I/Q demodulation and motor control algorithms.
Can the LTC1407ACMSE-1#TRPBF operate with an external reference voltage?
Yes, the LTC1407ACMSE-1#TRPBF supports external reference override: apply 2.55V to VREF (Pin 3) to disable the internal 2.5V bandgap and use an external reference up to VDD. With a 3.3V external reference and VDD ≥ 3.3V, SINAD improves to 73.5dB at 100kHz, enhancing dynamic performance for demanding RF applications.
What are the power states and wake-up behavior of the LTC1407ACMSE-1#TRPBF?
The LTC1407ACMSE-1#TRPBF offers three power states: active (4.7mA), nap (1.1mA), and sleep (2.0μA). Wake-up from sleep requires two SCK pulses and 2ms for VREF to settle; nap mode wakes instantly. All states retain register configuration, allowing rapid resumption of acquisition without reinitialization.
Is the LTC1407ACMSE-1#TRPBF pin-compatible with other variants in the LTC1407 family?
Yes, the LTC1407ACMSE-1#TRPBF shares identical pinout and footprint with LTC1407CMSE-1#TRPBF (12-bit), LTC1407AIMSE-1#TRPBF (–40°C to 85°C), and LTC1407IMSE-1#TRPBF. All variants use the same 10-lead MSOP package and functionally compatible timing and interface logic, enabling drop-in upgrades or temperature grade swaps.
