Product details
Overview
LTC1407AIMSE-1#TRPBF from Analog Devices (formerly Linear Technology) is a 14-bit, 3Msps simultaneous-sampling dual-channel ADC with two 1.5Msps differential input pairs, ±1.25V input range, 80dB CMRR at 100kHz, 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 phase-coherent sampling.
For engineers reviewing the LTC1407AIMSE-1#TRPBF datasheet, LTC1407AIMSE-1#TRPBF pinout, LTC1407AIMSE-1#TRPBF application, or LTC1407AIMSE-1#TRPBF equivalent, key selection criteria include simultaneous differential sampling timing skew (<200ps), internal 2.5V reference stability (±15ppm/°C), 73.5dB SINAD at 100kHz, 14-bit no-missing-codes resolution, and MSOP-10 thermal performance (θJA = 40°C/W).
Technical Context
The LTC1407AIMSE-1#TRPBF implements two independent sample-and-hold circuits triggered synchronously on the rising edge of CONV, enabling true simultaneous acquisition across CH0 and CH1. Each channel converts at 1.5Msps using a pipelined architecture with 32-clock serial output framing compatible with standard SPI interfaces.
It integrates a factory-trimmed 2.5V bandgap reference with external overdrive capability (2.55V–VDD), supports both internal and external references, and delivers 76.3dB SFDR at 100kHz while maintaining 5MHz full linear bandwidth and 50MHz full power bandwidth under differential input conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - guarantees monotonicity and full 16384-code dynamic range for precision measurement. |
| Sampling Rate | 3Msps aggregate / 1.5Msps per channel - enables real-time capture of signals up to 5MHz linear bandwidth. |
| Differential Input Range | ±1.25V - supports AC-coupled single-supply sensor interfaces without external level-shifting circuitry. |
| Common Mode Rejection | 80dB at 100kHz - suppresses ground-loop noise and enables accurate differential measurements in noisy industrial environments. |
| Power Consumption | 4.7mA active / 10μW sleep - allows battery-powered operation with rapid wake-up (2ms VREF settling) and low thermal dissipation. |
| Aperture Skew | 200ps max between CH0 and CH1 - ensures sub-degree phase alignment critical for I/Q demodulation and motor control. |
| SINAD | 72.0dB typical at 100kHz - translates to ~11.7 effective bits for high-fidelity signal reconstruction. |
Pinout & Package
Package: 10-lead plastic MSOP (MSE), exposed pad (Pin 11) soldered to PCB ground plane for thermal and electrical integrity. θJA = 40°C/W, TJMAX = 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0+ | Noninverting analog input, Channel 0 | Differential pair with CH0–; accepts 0V to VDD absolute voltage with ±1.25V swing relative to CH0–. |
| CH0– | Inverting analog input, Channel 0 | Differential complement to CH0+; defines common-mode baseline and enables rejection of shared noise. |
| VREF | 2.5V internal reference output | Bypassed with 10μF capacitor; can be overdriven by external 2.55V–VDD reference for improved accuracy or scaling. |
| CH1+ | Noninverting analog input, Channel 1 | Simultaneously sampled with CH0+; identical electrical specs support matched dual-channel acquisition. |
| CH1– | Inverting analog input, Channel 1 | Provides second differential pair; enables time-aligned dual-signal capture for phase-sensitive applications. |
| GND (Pins 6 & 11) | Analog/digital ground & exposed pad | Single low-impedance return path for analog sampling currents and digital output switching noise. |
| VDD | 3V supply input | Powers entire device; requires local 10μF + 0.1μF ceramic bypassing to minimize supply-induced conversion errors. |
| SDO | Three-state serial data output | 2's complement format; outputs 32 clocks per dual-conversion cycle; Hi-Z when SCK inactive. |
| SCK | Serial clock input | Rising-edge synchronized; controls data shift-out timing and wakes device from nap/sleep modes. |
| CONV | Convert start trigger | Rising-edge initiates simultaneous sampling; pulse count determines shutdown mode entry (2 pulses → nap, ≥4 → sleep). |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous differential sampling | Enables coherent multi-channel acquisition for I/Q demodulation and multiphase motor current sensing without inter-channel timing skew. |
| Internal 2.5V bandgap reference | Factory-trimmed to ±15ppm/°C drift and 600μV/V line regulation - eliminates need for external reference in cost-sensitive portable designs. |
| 3-wire serial interface | Compatible with standard SPI controllers; 32-clock frame delivers both 14-bit results without additional framing overhead or protocol complexity. |
| Sleep mode (10μW) | Reduces system standby power by >99% versus active mode - extends battery life in intermittent-sampling instrumentation. |
| 80dB CMRR at 100kHz | Allows direct connection to unshielded transducer outputs in electrically noisy environments such as industrial motor drives or telecom base stations. |

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, single-supply 2.7–5.5V, no internal reference, SPI-compatible but no sleep mode | Lower speed, higher resolution; requires external reference and biasing for differential inputs | Select when DC accuracy > speed; avoid if simultaneous sampling timing skew <500ps is required. |
| AD7357BRUZ | 14-bit, 4.25Msps dual-channel, 3.3V supply, 85dB CMRR, integrated reference buffer, no sleep mode | Higher speed and CMRR; larger 20-lead TSSOP package; higher 12.5mA active current | Select for higher SNR (75dB) and tighter CMRR in fixed-power industrial systems; not suitable for ultra-low-power portable use. |
Compared with ADS8327IPW and AD7357BRUZ, the LTC1407AIMSE-1#TRPBF uniquely balances 14-bit resolution, 3Msps aggregate sampling, 10μW sleep power, and MSOP-10 footprint - making it optimal for battery-constrained, phase-coherent dual-channel acquisition where thermal and board space are critical.

FAQ
What is the operating temperature range for the LTC1407AIMSE-1#TRPBF?
The LTC1407AIMSE-1#TRPBF is specified for operation from –40°C to +85°C, matching the "I" grade industrial temperature range. This is confirmed in the Order Information table and Absolute Maximum Ratings section of the datasheet, where LTC1407I-1 and LTC1407AI-1 variants share this range. The "A" suffix denotes improved 14-bit accuracy specifications over the base LTC1407-1.
Does the LTC1407AIMSE-1#TRPBF support external reference voltage?
Yes, the LTC1407AIMSE-1#TRPBF supports external reference voltage via the VREF pin (Pin 3). The internal 2.5V reference can be overdriven by an external source between 2.55V and VDD (max 3.6V), as stated in the Internal Reference Characteristics table and Applications Information section. This allows improved accuracy or custom input range scaling when needed.
How does the LTC1407AIMSE-1#TRPBF enter sleep mode?
The LTC1407AIMSE-1#TRPBF enters sleep mode when four or more CONV pulses are applied while SCK is held in a fixed high or low state. This is explicitly defined in the Pin Functions description for Pin 10 (CONV) and verified in the Nap/Sleep Mode Waveforms diagram. Sleep mode draws only 10μW, and VREF settles in 2ms after wake-up.
What is the maximum allowable analog input voltage for CH0+ and CH1+ pins?
The absolute voltage on CH0+, CH0–, CH1+, and CH1– must remain within 0V to VDD (2.7V to 3.6V), per Absolute Maximum Ratings and Analog Input specifications. While the differential swing is limited to ±1.25V, each pin may swing anywhere from ground to the supply rail - enabling flexible single-supply AC coupling without mid-rail bias generation.
Is the LTC1407AIMSE-1#TRPBF pin-compatible with the LTC1407-1 series?
Yes, the LTC1407AIMSE-1#TRPBF shares identical pinout, package (MSOP-10), and functional interface with all LTC1407-1 and LTC1407A-1 variants, including LTC1407CMSE-1#TRPBF and LTC1407IMSE-1#TRPBF. The "A" denotes enhanced 14-bit performance specifications, not mechanical or electrical interface changes - confirmed in the Pin Configuration and Ordering sections.
