Product details
Overview
LTC1407AHMSE#PBF from Analog Devices (formerly Linear Technology) is a 14-bit, 3Msps simultaneous-sampling dual-channel ADC with two fully differential inputs, 1.5Msps per channel throughput, 80dB CMRR at 100kHz, and operation from a single 3V supply. It features internal 2.5V bandgap reference, 3-wire serial interface, and Sleep mode consuming only 10μW - ideal for high-speed portable data acquisition in multiphase motor control and I/Q demodulation.
For engineers reviewing the LTC1407AHMSE#PBF datasheet, LTC1407AHMSE#PBF pinout, LTC1407AHMSE#PBF application, or LTC1407AHMSE#PBF equivalent, key selection criteria include simultaneous sampling accuracy, 14-bit resolution with ±0.5 LSB integral linearity over –40°C to +125°C, differential input range of 0V–2.5V, and MSOP-10 package compatibility with high-density PCB layouts.
Technical Context
The LTC1407AHMSE#PBF integrates two independent sample-and-hold circuits triggered simultaneously on the rising edge of CONV, enabling true time-aligned acquisition across CH0 and CH1. Its architecture supports unipolar differential conversion with internal 2.5V reference or external overdrive up to VDD, maintaining 73.5dB SINAD at 750kHz input under H-grade conditions.
Timing is governed by a 3-wire serial interface (SCK, CONV, SDO) where conversion completes in 32 SCLK cycles, and aperture skew between channels is tightly controlled at 200ps. The device achieves full-power bandwidth of 50MHz and full linear bandwidth of 5MHz, with analog input common-mode range spanning 0V to VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - delivers 153μV LSB step size for precise voltage measurement in sensor and control systems. |
| Sampling Rate | 3Msps aggregate (1.5Msps per channel) - enables real-time capture of fast transients in motor phase currents or RF baseband signals. |
| Integral Linearity Error | ±0.5 LSB max - ensures monotonicity and minimizes harmonic distortion in closed-loop feedback applications. |
| Common Mode Rejection | 80dB at 100kHz - suppresses ground loop noise and EMI in industrial environments with shared power/ground domains. |
| Supply Current | 5.2mA typical active mode, 2.0μA Sleep mode - supports battery-powered instrumentation with extended runtime. |
| Input Voltage Range | 0V to 2.5V differential, 0V to VDD absolute - simplifies single-supply signal conditioning without level-shifting circuitry. |
| SINAD | 73.5dB at 750kHz (H-grade) - meets dynamic range requirements for 12+ ENOB in communications and test equipment. |
Pinout & Package
Package: 10-lead MSOP (MSE), exposed pad tied to GND - provides low thermal resistance (θJA = 40°C/W) and robust EMI immunity in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0+, CH0– | Differential Input Channel 0 | Simultaneously sampled pair; accepts 0V–2.5V differential swing with 0V–VDD common-mode range - enables direct connection to isolated current-sense amplifiers. |
| CH1+, CH1– | Differential Input Channel 1 | Independent simultaneous sampling path; matched offset/gain to CH0 (±1 LSB match) - critical for phase-aligned I/Q signal capture. |
| VREF | Internal 2.5V Reference Output | Bypassed with 10μF capacitor; supports external overdrive ≥2.55V - allows flexible input span scaling while maintaining accuracy. |
| GND (Pins 6 & 11) | Analog/Digital Ground + Exposed Pad | Single-point grounding node; exposed pad must be soldered to PCB ground plane - essential for noise-free 14-bit performance. |
| VDD (Pin 7) | 3V Power Supply | Supplies entire IC; requires local 10μF + 0.1μF bypassing - prevents digital switching noise from corrupting analog conversion. |
| SDO (Pin 8) | Three-State Serial Data Output | Outputs 32-bit frame (14-bit CH0 + 14-bit CH1) synchronized to SCK rising edge - compatible with standard SPI controllers without protocol translation. |
| SCK (Pin 9) | Serial Clock Input | Drives internal timing logic; minimum pulse width 2ns - supports high-speed data streaming up to 1.5Msps per channel. |
| CONV (Pin 10) | Convert Start / Power Mode Control | Rising edge initiates simultaneous sampling; multiple pulses enter Nap (3mW) or Sleep (10μW) modes - enables adaptive power management. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Sampling | True time-aligned acquisition across both channels with 200ps aperture skew - preserves phase relationship in multiphase systems. |
| Low-Power Sleep Mode | 10μW quiescent power with 2ms VREF settling after wake-up - extends battery life in portable DAQ without sacrificing startup latency. |
| High CMRR at RF Frequencies | 80dB rejection at 100kHz, >60dB maintained up to 1MHz - eliminates interference from switching power supplies and clock harmonics. |
| Flexible Reference Architecture | Internal 2.5V bandgap (15ppm/°C tempco) or external overdrive (2.55V–VDD) - enables precision scaling for varying sensor output ranges. |
| Robust Input Protection | Analog inputs tolerate –0.3V to VDD+0.3V with clamp diodes; handles >100mA transient currents without latch-up - enhances field reliability. |

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 |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1Msps, single-channel SAR ADC with internal reference; no simultaneous sampling capability. | Requires external multiplexer for dual-channel capture, introducing timing skew and reduced effective throughput. | Select when higher resolution (16-bit) is prioritized over simultaneity and speed; not suitable for phase-critical I/Q or motor control. |
| AD7380BCPZ-RL7 | 14-bit, 4Msps, dual-channel simultaneous-sampling SAR ADC; operates from 3.3V supply, wider temp range (–40°C to +125°C). | Higher sampling rate and improved SNR (76dB) but requires 3.3V supply and lacks Sleep mode (150μW standby). | Prefer for new designs needing margin in speed/SNR; LTC1407AHMSE#PBF remains optimal for 3V systems with ultra-low-power sleep requirements. |
Compared with ADS8860IDRCT and AD7380BCPZ-RL7, the LTC1407AHMSE#PBF uniquely balances 14-bit resolution, true simultaneity, 3V operation, and 10μW Sleep mode - making it irreplaceable in space-constrained, battery-sensitive, phase-coherent applications.

FAQ
What is the operating temperature range of the LTC1407AHMSE#PBF?
The LTC1407AHMSE#PBF is rated for operation from –40°C to +125°C, meeting automotive and industrial requirements. This H-grade specification is confirmed in the Absolute Maximum Ratings table and applies to all converter characteristics including integral linearity (±0.5 LSB), gain error (±80 LSB), and SINAD performance across the full range.
Does the LTC1407AHMSE#PBF support external reference voltage?
Yes, the LTC1407AHMSE#PBF supports external reference overdrive on the VREF pin (Pin 3) from 2.55V up to VDD. When using an external reference, the differential input range scales proportionally (e.g., 3.3V reference yields 0V–3.3V span), and the device maintains specified accuracy with proper bypassing per Figure 2 in the datasheet.
How does the Sleep mode function on the LTC1407AHMSE#PBF?
Sleep mode on the LTC1407AHMSE#PBF is activated by applying four or more CONV pulses while SCK is held static (high or low), reducing supply current to 2.0μA and power dissipation to 10μW. VREF settles in 2ms after wake-up, and full performance resumes within one conversion cycle - verified in the Power Requirements and Timing Characteristics sections.
What is the maximum analog input frequency supported by the LTC1407AHMSE#PBF?
The LTC1407AHMSE#PBF has a full-power bandwidth of 50MHz and full linear bandwidth of 5MHz. For 14-bit accuracy, the device maintains ≥68dB SINAD up to 5MHz; at 750kHz input, it achieves 73.5dB SINAD (H-grade), making it suitable for baseband signals in communications and motor control up to ~1.5MHz fundamental frequency.
Can the LTC1407AHMSE#PBF be used with a 3.3V supply?
No - the LTC1407AHMSE#PBF is specified for 2.7V to 3.6V operation, but its internal reference and analog performance are optimized for 3V nominal supply. At 3.3V, VREF overdrive capability increases, but offset/gain errors and dynamic specifications degrade beyond datasheet limits; Linear Technology explicitly recommends 3V operation in the Applications Information section.
