## What is the resolution of a 24-bit ADC?

The ADS1240 and ADS1241 are precision, wide dynamic range, delta-sigma, Analog-to-Digital (A/D) converters with 24-bit resolution operating from 2.7V to 5.25V power supplies. The delta-sigma A/D converter provides up to 24 bits of no missing code performance and effective resolution of 21 bits.

When you see analog input DAQ devices from various manufacturers called 12-bit, 16-bit, or 24-bit, it generally just means they have an ADC (analog to digital converter) that returns that many bits. When an ADC chip returns 16 bits, it is probably better than a 12-bit converter, but not always.

ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.

A 10-bit ADC has 210, or 1,024 possible output codes. So the resolution is 5V/1,024, or 4.88mV; a 12-bit ADC has a 1.22mV resolution for this same reference. Types of ADCs. ADCs come in various speeds, use different interfaces, and provide differing degrees of accuracy.

### What is 24 bit resolution?

Audio resolution is measured in bits, not in Hz, Herz, or kHz. Similarly, 24-bit audio can record 16,777,216 discreet values for loudness levels (or a dynamic range of 144 dB), versus 16-bit audio which can represent 65,536 discrete values for the loudness levels (or a dynamic range of 96 dB).

### What is 8bit resolution?

Resolution is generally quantified by the number of bits in the analog-to-digital converter (ADC). The resolution is equal to 2 raised to the power of the number of bits. As such, an 8-bit converter has a resolution of 28 or 256:1.

What is step size?

The step size is the voltage difference between one digital level (i.e. 0001) and the next one (i.e. 0010 or 0000). For example if an ADC has a step size of 1 Volt an input of 1 volt will produce an output, in a 4 bit converter, of 0001.
