Save up to 91 power and up to 50 percent space with industry’s fastest 20-bit SAR ADC

USA: Engineers can achieve the industry's highest resolution and fastest sampling rate at the lowest power with the MAX11905, a 20-bit, 1.6Msps successive approximation register (SAR) analog-to-digital converter (ADC) from Maxim Integrated Products Inc.

Typically, when engineers require high-precision data conversion, they turn to a delta-sigma ADC. However, to produce high precision and wide dynamic range, those ADCs must consume at least 100mW of power. In contrast, the MAX11905 SAR ADC consumes only 9mW-a 91 percent power savings.

With this power savings comes very high (20-bit) precision and the fastest sampling (1.6Msps) rate available. The MAX11905 also integrates internal reference buffers, which reduces cost and time to market, and saves up to 50 percent space compared to competitive discrete solutions. With this versatility, the MAX11905 is ideal for a wide range of applications, including process control, automatic test equipment, medical instrumentation, and battery-powered devices.

Key advantages include:

High speed: The MAX11905 enables 1.6Msps throughout with no latency and settling time limitation.

High performance: The ADC achieves 98.3dB signal-to-noise ratio (SNR) and -123dB THD; improves static and dynamic performance; guarantees monotonic function; and provides best-in-class power consumption.

Versatility: The SAR ADC delivers high 20-bit resolution with no missing codes, at 1.6Msps of speed, at 9mW of power, enabling flexibility in designs without compromises.

Simplified designs: the MAX11905 integrates internal reference buffers, reducing design time and cost.
