ADC121C021CIMK/NOPB Key Specifications

Resolution: 12 Bits (No Missing Codes)

Conversion Time: 1µs (Typ)

INL & DNL: ±1 LSB (Max) (Up to 22ksps)

Throughput Rate: 188.9 ksps (Max)

Power Consumption (at 22 ksps)

3V Supply: 0.26 mW (Typ)

5v Supply: 0.78 mW (Typ)

 

The ADC has 12-bit resolution and operates from a single 1.8V to 5.5V power supply.

It has a conversion rate of up to 200 ksps, with a low-power shutdown mode that reduces power consumption during idle periods.

The input voltage range is 0V to VREF, where VREF can be varied between 1.8V and 5.5V.

The device has an internal reference voltage of 2.5V, which can be used as a reference for the ADC.

The ADC supports both software and hardware trigger modes for initiating conversions.

It also features a programmable channel scanning mode, which enables sequential sampling of multiple channels without requiring external control signals.

The temperature range for operation is -40°C to +125°C.

Applications for this ADC include industrial process control, medical instrumentation, portable equipment, consumer electronics, and data acquisition systems.
