Product details
Overview
LTC1407AHMSE#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit, 3Msps simultaneous-sampling dual-channel ADC with two fully differential inputs, 80dB CMRR at 100kHz, 0V–2.5V unipolar input range, and operation on a single 3V supply. It delivers 1.5Msps throughput per channel while consuming only 5.2mA active current, making it suitable for high-speed portable data acquisition and multiphase motor control systems.
For engineers reviewing the LTC1407AHMSE#TRPBF datasheet, LTC1407AHMSE#TRPBF pinout, LTC1407AHMSE#TRPBF application, or LTC1407AHMSE#TRPBF equivalent, key selection criteria include simultaneous sampling accuracy, 14-bit resolution with ±0.5 LSB integral linearity over –40°C to +125°C, internal 2.5V reference stability (±15 ppm/°C), and MSOP-10 package compatibility with space-constrained industrial sensor interfaces.
Technical Context
The LTC1407AHMSE#TRPBF integrates two independent sample-and-hold circuits triggered simultaneously on the rising edge of CONV, enabling true time-aligned acquisition across CH0 and CH1. Each channel converts at 1.5Msps using a pipelined architecture with 32-clock serial output timing.
It features an on-chip 2.5V bandgap reference with external overdrive capability (2.55V–VDD), supports 3-wire SPI-compatible serial interface (SCK/CONV/SDO), and provides three power modes: Active (5.2mA), Nap (1.2mA), and Sleep (10μA), all validated across its full –40°C to +125°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes; enables 153μV LSB step size for precise low-amplitude signal digitization. |
| Sampling Rate | 3Msps total (1.5Msps per channel); supports real-time capture of fast transients in I/Q demodulation and motor phase monitoring. |
| Integral Linearity Error | ±0.5 LSB max over temperature; ensures <0.003% end-point nonlinearity for calibrated measurement systems. |
| Common Mode Rejection | 80dB at 100kHz; suppresses ground-loop noise and EMI in industrial analog front-ends without external instrumentation amps. |
| Supply Current | 5.2mA typical in active mode; allows battery-powered operation with >20-hour runtime on a 100mAh cell at 1.5Msps sustained rate. |
| Reference Voltage | 2.5V internal bandgap (±15 ppm/°C tempco); eliminates need for external reference IC in cost-sensitive designs. |
| Input Range | 0V to 2.5V differential; compatible with single-supply op-amps (e.g., LT1806) driving directly into CH0+/CH0– and CH1+/CH1–. |
Pinout & Package
Package: 10-lead MSOP (MSE), exposed pad (Pin 11) connected to GND. Requires soldering exposed pad to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0+ (Pin 1) | Noninverting input, Channel 0 | Differential pair with CH0–; accepts 0–VDD absolute voltage, contributes to 0–2.5V differential swing. |
| CH0– (Pin 2) | Inverting input, Channel 0 | Completes differential pair; common-mode rejection relies on matched trace lengths to Pin 1. |
| VREF (Pin 3) | Internal 2.5V reference output | Bypassed with 10μF + 0.1μF capacitors; can be overdriven by external 2.55–VDD reference for improved accuracy. |
| CH1+ (Pin 4) | Noninverting input, Channel 1 | Simultaneously sampled with CH0+; enables phase-coherent dual-channel acquisition for vector measurements. |
| CH1– (Pin 5) | Inverting input, Channel 1 | Matches CH0– functionally; aperture skew between CH0 and CH1 is ≤200ps for timing-critical applications. |
| GND (Pins 6, 11) | Analog/digital ground & exposed pad | Pins 6 and 11 must connect to solid ground plane; exposed pad is electrically GND and critical for thermal dissipation. |
| VDD (Pin 7) | 3V supply input | Single supply powers entire device; requires local 10μF + 0.1μF bypassing to minimize switching noise coupling. |
| SDO (Pin 8) | Three-state serial data output | Outputs 32-bit frame (14-bit CH0 + 14-bit CH1) aligned to SCK rising edges; Hi-Z when SCK inactive. |
| SCK (Pin 9) | Serial clock input | Drives conversion sequencing and data readout; minimum pulse width 2ns; controls Nap/Sleep entry via pulse count. |
| CONV (Pin 10) | Convert start trigger | Rising edge initiates simultaneous sampling; multiple pulses with fixed SCK state enter Nap (2 pulses) or Sleep (≥4 pulses). |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous sampling | Guarantees sub-200ps inter-channel aperture skew-critical for accurate phase difference measurement in motor control and I/Q demodulation. |
| 80dB CMRR at 100kHz | Enables direct connection to noisy industrial sensors without external instrumentation amplifiers, reducing BOM and layout complexity. |
| 3-wire serial interface | Eliminates CS/SS pin requirement; simplifies microcontroller GPIO usage and reduces routing congestion in dense PCB layouts. |
| 10μW Sleep mode | Extends battery life in portable DAQ systems; wake-up latency includes 2ms VREF settling time after Sleep-to-Active transition. |
| MSOP-10 package | 10-pin, 3mm × 3mm footprint with exposed pad-fits tight spaces in handheld test equipment and embedded controllers. |

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 |
|---|---|---|---|
| AD7357BRUZ | 14-bit, 4.2Msps dual SAR ADC; requires external reference and separate power supplies for analog/digital domains. | Higher speed but larger 24-lead TSSOP package; lacks integrated reference and Sleep mode power optimization. | Choose AD7357BRUZ when >3Msps aggregate throughput is required and board space allows larger footprint. |
| ADS8326IPW | 16-bit, 1Msps dual SAR ADC; single-supply 3V operation, no internal reference, 16-lead TSSOP package. | Higher resolution but lower speed and no simultaneous sampling guarantee; CMRR not specified beyond DC. | Choose ADS8326IPW for DC-precision applications like calibration equipment where 16-bit linearity outweighs timing alignment needs. |
Compared with AD7357BRUZ and ADS8326IPW, the LTC1407AHMSE#TRPBF uniquely combines 14-bit resolution, guaranteed simultaneous sampling, integrated 2.5V reference, and ultra-low Sleep power in a compact MSOP-10-making it optimal for portable, phase-sensitive, and thermally constrained industrial systems.

FAQ
What is the operating temperature range of the LTC1407AHMSE#TRPBF?
The LTC1407AHMSE#TRPBF is rated for operation from –40°C to +125°C. This H-grade specification is confirmed in the Absolute Maximum Ratings table and applies to all dynamic and DC specifications-including integral linearity (±0.5 LSB), gain error (±80 LSB), and supply current (5.2mA typ)-across the full range.
Does the LTC1407AHMSE#TRPBF support external reference voltage?
Yes, the LTC1407AHMSE#TRPBF supports external reference voltage applied to the VREF pin (Pin 3). The external reference must be between 2.55V and VDD (max 3.6V), and will override the internal 2.5V bandgap. When using external reference, the full-scale input range becomes equal to the applied reference voltage.
How does the Sleep mode work on the LTC1407AHMSE#TRPBF?
Sleep mode on the LTC1407AHMSE#TRPBF is entered by applying ≥4 pulses to the CONV pin while holding SCK in a fixed high or low state. In Sleep mode, supply current drops to 10μA. Wake-up requires one SCK pulse, followed by 2ms VREF settling time before valid conversions resume.
What is the maximum analog input frequency supported by the LTC1407AHMSE#TRPBF?
The LTC1407AHMSE#TRPBF has a full-power bandwidth of 50MHz and full linear bandwidth of 5MHz. At 750kHz input frequency, SINAD is 73.5dB (typ) and THD is –85dB (typ), confirming usable performance well into the MHz range for communication and motor control applications.
Is the LTC1407AHMSE#TRPBF pin-compatible with the LTC1407A series?
Yes, the LTC1407AHMSE#TRPBF shares identical pinout, package (MSOP-10), and functional interface with all LTC1407A variants (e.g., LTC1407AIMSE#TRPBF). Differences are limited to temperature grade (–40°C to +125°C) and guaranteed AC/DC specs over that extended range-not physical or logical compatibility.
