Product Information

Description

View system block diagrams:

The TMDXMDKEK1258 Electrocardiogram (ECG) Analog Front End (AFE) module module is part of the ECG medical development kit (MDK), which consists of the ECG AFE module, a a processor board (C5505 DSP evaluation module), and a set of collateral and C5505 based application sample code to implement the ECG application. The ECG MDK delivers a complete signal chain solution to enable ECG developers to build a complete ECG system quickly for evaluation and get to production faster.

Features

ECG AFE module key components
  1. ADS1258 – 16 channel, 24-bit sigma delta analog-to-digital converter (ADC)
  2. INA 128 - precision, low power instrumentation amplifier
  3. PCA9535 - remote 16-bit I2C and SMBus low-power I/O expander
  4. TLV3404 - nanopower open drain output comparator
  5. REF5025 - low-noise, very low drift precision voltage reference

The ADS1258 ADC is one of 27 components on the TMDXMDKEK1258 ECG AFE module. The input signals are processed by the ADS1258, which provides for 24 bits of resolution with no missing codes. Additionally, the ADS1258 provides very low latency, industry-leading speed and noise performance as well as a very low power consumption level – making it very suitable for portable applications.

A high-quality reference voltage is essential for achieving the best performance from the ADS1258. Noise and drift can degrade overall system performance. The REF5025 precision voltage reference provides excellent temperature drift (3ppm/°C), low noise of 3uVpp/V and 0.05% accuracy.

The INA128 provides not only for high input impedance to reduce loading of the signal, but also for high common mode rejection required for noise rejection when used in conjunction with low pass filters.

The ECG AFE module can seamlessly connect to various processor platforms, such as the C5505 EVM or the OMAP35xx Zoom Development Kit, through standard interface.
