MAX122BCWG

The MAX122BCWG from Analog Devices is a complete 12-bit analog-to-digital converter (ADC) with an on-chip track/hold (T/H) and a low-drift voltage reference. It offers fast conversion speeds and low power consumption, achieving throughput rates of up to 333kSPS with a 2.6µs conversion time.

This ADC accepts analog input voltages from -5V to +5V and requires only external decoupling capacitors. The MAX122 operates with clock frequencies in the 0.1MHz to 5MHz range. It features a standard microprocessor (µP) interface with three-state data outputs compatible with 12-bit data buses, and can interface directly to FIFO buffers.

Key electrical specifications include 12-bit resolution, no missing codes over temperature, and a low-drift internal reference. It boasts a SINAD of 70dB (min) and THD of -77dB (max). The device consumes only 210mW of power.

The MAX122BCWG is available in a 24-pin SOIC package, designed for surface mounting. Its operating temperature range is 0°C to 70°C. This ADC is suitable for applications such as digital-signal processing, audio and telecom processing, speech recognition, high-speed data acquisition, spectrum analysis, and data logging systems.
