TEXAS INSTRUMENTS 模数转换器(ADC) ADS7831P

ADS7831P概述

    # ADS7831 12-Bit 600kHz Sampling CMOS Analog-to-Digital Converter
    Product Introduction
    The ADS7831 is a highly efficient 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) fabricated using advanced CMOS technology. This ADC integrates essential components such as a sample-and-hold circuit (S/H), a reference generator, a clock, and a parallel data interface, enabling direct integration with microprocessors. Designed for industrial applications, the ADS7831 supports a standard ±2.5V input range, ensuring excellent performance within ±5V supply systems. Available in both 28-pin plastic DIP and SOIC packages, the device is fully specified for operation across the industrial temperature range of –40°C to +85°C.
    Key applications include data acquisition systems, industrial automation, communication equipment, and instrumentation requiring high-speed and high-resolution analog signal conversion.
    Technical Parameters
    The ADS7831 offers impressive performance metrics:
    | Parameter | Specification |

    | Resolution | 12 bits |
    | Analog Input Voltage Range | ±2.5 V |
    | Input Impedance | 3.1 kΩ |
    | Throughput Speed | Up to 600 kHz |
    | Conversion Time | 1.3 μs |
    | Total Unadjusted Error | ±10 LSB |
    | SFDR (Spurious-Free Dynamic Range) | 77-87 dB |
    | THD (Total Harmonic Distortion) | –85 to –77 dB |
    | Signal-to-(Noise+Distortion) | 69-71 dB |
    | Signal-to-Noise Ratio | 69-72 dB |
    | Usable Bandwidth | 1.6 MHz |
    | Full-Power Bandwidth | 15 MHz |
    | Aperture Delay | 20 ns |
    | Overvoltage Recovery | 250 ns |
    This ADC operates under dual power supplies: +VDIG = +VANA = +5V and –VANA = –5V. The device achieves low power dissipation of 220-275 mW at a 600 kHz sampling frequency and ensures compatibility with temperatures from –40°C to +85°C.
    Product Features and Advantages
    The ADS7831 stands out with its high-throughput rate, excellent dynamic performance, and robust design:
    - High Throughput Rate: Supports up to 600 kHz, making it suitable for high-speed data acquisition.
    - Dynamic Performance: Offers superior signal integrity with SFDR up to 94 dB and THD down to –98 dB.
    - Temperature Stability: Fully specified for harsh environments, providing reliable performance over a wide temperature range.
    - Low Power Consumption: Minimal power consumption ensures efficient energy usage, ideal for portable and battery-operated systems.
    - Wide Bandwidth: Capable of handling signals up to 15 MHz, extending application versatility.
    These features make the ADS7831 a compelling choice for precision measurement systems and industrial-grade applications where reliability and speed are critical.
    Application Cases and Usage Recommendations
