The ADS1299 is a low-noise, multichannel, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADS1299 incorporates all commonly-required features for electroencephalogram (EEG) applications. With its high levels of integration and exceptional performance, the ADS1299 enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.

The ADS1294/6/8/4R/6R/8R are a family of multichannel, simultaneous sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with built-in programmable gain amplifiers (PGAs), internal reference, and an onboard oscillator. The ADS1294/6/8/4R/6R/8R incorporates all of the features that are commonly required in medical electrocardiogram (ECG) and electroencephalogram (EEG) applications. With its high levels of integration and exceptional performance, the ADS1294/6/8/4R/6R/8R family enables the development of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.

The ADS1194/6/8 are a family of multichannel, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADS1194/6/8 have a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection. Additionally, any configuration of input channels can be selected for derivation of the right leg drive (RLD) output signal. The ADS1194/6/8 operate at data rates as high as 8kSPS, thereby allowing the implementation of software pace detection. Lead-off detection can be implemented internal to the device, either with a pull-up/pull-down resistor or an excitation current sink/source. Three integrated amplifiers generate the Wilson Center Terminal (WCT) and the Goldberger terminals (GCT) required for a standard 12-lead medical electrocardiogram (ECG).

The ADS1293 incorporates all features commonly required in portable, low-power medical, sports and fitness electrocardiogram (ECG) applications. With high levels of integration and exceptional performance, the ADS1293 enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. The ADS1293 features three high-resolution channels capable of operating up to 25.6ksps. Each channel can be independently programmed for a specific sample rate and bandwidth allowing users to optimize the configuration for performance and power. All input pins incorporate an EMI filter and can be routed to any channel via a flexible routing switch. Flexible routing also allows independent lead-off detection, right leg drive, and Wilson/Goldberger reference terminal generation without the need to reconnect leads externally. A fourth channel allows external analog pace detection for applications that do not utilize digital pace detection.

The ADS1220 eases overall analog design by integrating the full analog front end needed for most sensor types (temperature, pressure, weigh-scale, and others). At 24-bits of resolution, the ADS1220 features 2 differential or 4 single-ended inputs through a very flexible input multiplexer, a low-noise PGA, two programmable excitation current sources, an internal reference, an oscillator, a low-side bridge switch, and a precision temperature sensor. This high degree of integration into a single package makes the ADS1220 the ideal solution for thermocouple, RTD, pressure, and weigh-scale measurements at the 24-bit level. The limited set of SPI commands and register settings ease the design with ADS1220. As the ADS1220 can operate from a supply voltage as low as 2.3V and also offers low power consumption of less than 0.5mW, it is ideally suited for portable battery powered applications such as battery operated medical instrumentation.

The OPA313 and OPA314 family of op amps represents a new generation of low-cost, general purpose, micro-power operational amplifiers. Rail-to-rail input, very low noise (25 nV/√Hz at 1 kHz for OPA313; 14 nV/√Hz at 1kHz for OPA314), and low quiescent current (60µA for OPA313; 150µA for OPA314) make this family very attractive for a variety of battery-powered applications that require a good balance between cost and performance.
