Mingjiada in Stock | TI ADS1174IPAPT: 4-channel 16-bit synchronous analog-to-digital converter, ideal for high-precision data acquisition
I. ADS1174IPAPT Product Overview
The ADS1174IPAPT is a high-performance, four-channel, 16-bit Δ-Σ (Delta-Sigma) analog-to-digital converter (ADC) introduced by Texas Instruments. It supports data sampling rates up to 52 kSPS and enables synchronous sampling across all four channels. This device shares the same package as the eight-channel ADS1178 in the same series and is fully compatible with the high-performance 24-bit ADS1274 and ADS1278, facilitating future system upgrades.
The ADS1174IPAPT is housed in a 64-PowerTQFP (HTQFP-64) package, supports surface-mount technology, and operates within a temperature range of -40°C to +85°C, making it suitable for a wide range of harsh industrial environments.

III. ADS1174IPAPT Key Product Highlights
3.1 Synchronous Sampling with High Phase Coherence
The ADS1174IPAPT supports simultaneous sampling across all four channels, ensuring no phase delay differences between channels. It is particularly suitable for applications with strict phase accuracy requirements, such as three-phase power monitoring and synchronous multi-sensor data acquisition.
3.2 Flexible Dual-Mode Switching, Balancing Speed and Power Consumption
The device offers two selectable operating modes: High-Speed Mode (52 kSPS, 31 mW per channel) and Low-Power Mode (10 kSPS, only 7 mW per channel). Engineers can flexibly balance data acquisition speed and system power consumption based on the application scenario.
3.3 Outstanding DC and AC Performance
The Δ-Σ architecture, combined with a high-order chopper-stabilized modulator, achieves an offset voltage drift of 2 µV/°C and a gain drift of 2 ppm/°C, while maintaining a signal-to-noise ratio of 97 dB and total harmonic distortion of -105 dB. This meets the dual requirements of DC accuracy and AC performance in high-precision industrial measurements.
3.4 On-Chip FIR Digital Filter
The chip integrates a finite impulse response (FIR) digital filter, providing an available signal bandwidth of up to 90% of the Nyquist frequency and out-of-band rejection of up to 100 dB, effectively suppressing modulator noise and out-of-band signal noise.
3.5 Flexible Serial Interfaces and Daisy-Chain Support
Optional SPI or frame-synchronous serial interfaces facilitate connection to DSPs, FPGAs, and microcontrollers. Both interfaces support daisy-chain functionality, simplifying data readback design for systems with multiple ADS1174 or ADS1178 devices.
3.6 Synchronization Input Pin
The SYNC input control pin allows ADC conversions to be triggered in synchronization with external events, facilitating coordinated operation in multi-chip systems.
IV. ADS1174IPAPT Typical Application Scenarios
Thanks to its excellent overall performance, the ADS1174IPAPT is widely used in the following fields:
Power Monitoring: Three-phase power monitoring, power quality analysis, smart grid equipment
Medical Devices: Defibrillators, ECG monitors
Industrial Measurement: Pressure sensors, Coriolis flowmeters
Structural Analysis: Vibration/modal analysis, structural health monitoring
