说明

Texas Instruments 的 TLA2024IRUGT 是一款带 I2C 接口的 12 位 4 通道三角积分 ADC，采用 10 引脚 X2QFN 封装（2.0 x 1.5 mm）。它具有灵活的输入多路复用器（4 路单端或 2 路差分）、可编程增益放大器（1x/2x/4x/8x 至 x16）、内部电压基准、内部振荡器、128 SPS 至 3.3 kSPS 数据速率、150 uA 电源电流、2V 至 5.5V 电源范围以及 3 个引脚可选的 I2C 地址。单次或连续转换。典型功耗为 0.9 mW。工作温度 -40C 至 +85C。卷带包装。.

Texas Instruments 的 TLA2024IRUGT 是一款超小型、成本优化型 12 位三角积分 ADC，具有 4 通道输入多路复用器和可编程增益放大器，采用 10 引脚 X2QFN 封装，尺寸仅为 2.0 x 1.5 mm。它是 TLA202x 系列中通道密度最高的变体，提供 4 个单端或 2 个差分输入通道，每个通道的面积仅为 0.75 mm2。.

TLA2024 具有灵活的输入多路复用器，可配置为四个单端输入（AIN0-GND、AIN1-GND、AIN2-GND、AIN3-GND）或两个差分输入对（AIN0-AIN1、AIN2-AIN3）。多路复用器可通过 I2C 接口进行软件配置，允许对多个输入通道进行顺序扫描。.

集成的可编程增益放大器（PGA）提供 x1、x2、x4、x8 和 x16 增益设置（注：有些资料显示最高为 x16，而有些资料显示最大为 x8）。PGA 增益最大时，输入范围减小到 +/-256 mV（x8 时）或 +/-128 mV（x16 时），从而无需外部放大即可直接测量电流检测电阻、热电偶和桥式传感器的小信号。PGA 的输入范围从 +/-6.144V (x1) 到 +/-256 mV (x8)。.

该器件集成了电压基准、振荡器和 I2C 接口。内部 2.048V 基准电压提供 ADC 全量程基准电压。I2C 接口支持标准模式和快速模式，有三个引脚可选地址。.

TLA2024 提供 12 位分辨率，可编程数据速率为 128 SPS 至 3.3 kSPS。三角积分架构具有固有的抗锯齿和良好的噪声性能。INL 典型值为 1 LSB，满量程误差典型值为 0.05% FSR。保证 12 位内无缺码。.

0.9 mW 的典型功耗和单次转换模式使 TLA2024 适合功耗受限的应用。在单次转换模式下，器件在每次转换后都会自动关闭电源，从而在低采样率时将平均电流降至微安级。.

X2QFN 封装的焊盘面积仅为 3 平方毫米，是业内最小的 4 通道 12 位 ADC。因此，可直接放置在空间受限系统中的传感器节点上。.

TLA2024 与 TLA2021 和 TLA2022 采用相同的数据表 (SBAS975)。主要区别在于TLA2021 = 1 通道，无 PGA；TLA2022 = 1 通道，带 PGA；TLA2024 = 4 通道，带 PGA 和 MUX。.

**带 PGA 和多路复用器的Δ-Σ ADC：** 输入信号首先通过模拟多路复用器，模拟多路复用器从四种单端或两种差分输入配置中选择一种。然后，所选信号经 PGA 放大，经三角积分调制器数字化，再经 SINC 数字抽取滤波器滤波，产生 12 位输出字。.

**输入多路复用器：** 4:1（单端）或 2:1（差分）多路复用器由配置寄存器中的 MUX[2:0] 位控制。通道切换在转换结果有效之前需要一定的沉淀时间，通常为一个转换周期。.

**PGA 操作：** PGA 在调制器之前放大输入信号。增益为 x1 时，满量程输入范围为 +/-6.144V（远超过 VDD，但受限于绝对最大额定值 VDD+0.3V）。x2 增益时+/-4.096V.在 x4 时+/-2.048V.x8 时：+/-1.024V（某些信号源：+/-256mV）。增益越高，输入范围越小，但对小信号的有效分辨率越高。PGA 输入共模范围必须在 GND-0.1V 至 VDD+0.1V 之间。.

**转换和数据格式：** 12 位转换结果以 16 位二进制格式输出，左对齐。PGA = x1 时，1 LSB = 187.5 uV (6.144V / 32768)。PGA = x8 时，1 LSB = 23.4 uV（1.024V / 32768，如果 12 位有效）。.

**I2C 协议：** 写入 16 位配置寄存器以设置 MUX、PGA、模式和数据速率。读取 2 个字节（16 位）的转换结果。写入 1 时，OS 位开始单次转换。ALERT/RDY 引脚可发出转换完成或超出范围的信号。.

应用 说明
多传感器系统监测器 同时监控 4 个系统电压（电池、3.3V 电压轨、5V 电压轨、12V 电压轨）；电阻分压器将电压扩展至 2.048V 范围；通过通道进行 MUX 排序；I2C 向系统控制器报告；单个 X2QFN 替代 4 个分立比较器
电流感应分流电阻器 使用差分输入对测量电流检测电阻器上的电压；PGA x8 放大毫伏级分流电压；12 位分辨率在 x8 时提供 23uV LSB；使用 2 个差分对监控 2 个电流通道
便携式仪器前端 手持式仪器可测量 4 个传感器通道；超小型 X2QFN 适合笔型外壳；150uA 电流消耗可节省电池；10 SPS 的单次拍摄模式可将平均电流降至微安；I2C 接口可连接低功耗 MCU
