DESCRIPTION
16-Bit, 2Msps, Low Power
SAR ADC with 96.2dB SNR
The LTC2380-16 is a low noise, low power, high speed
16-bit successive approximation register (SAR) ADC.
Operating from a 2.5V supply, the LTC2380-16 has a
±VREF fully differential input range with VREF ranging from
2.5V to 5.1V. The LTC2380-16 consumes only 19mW and
achieves ±0.6LSB INL maximum, no missing codes at
16 bits with 96.2dB SNR.
The LTC2380-16 has a high speed SPI-compatible serial
interface that supports 1.8V, 2.5V, 3.3V and 5V logic while
also featuring a daisy-chain mode. The fast 2Msps through-
put with no cycle latency makes the LTC2380-16 ideally
suited for a wide variety of high speed applications. An
internal oscillator sets the conversion time, easing external
timing considerations. The LTC2380-16 automatically pow-
ers down between conversions, leading to reduced power
dissipation that scales with the sampling rate.
The LTC2380-16 features a unique digital gain compres-
sion (DGC) function, which eliminates the driver amplifier’s
negative supply while preserving the full resolution of the
ADC. When enabled, the ADC performs a digital scaling
function that maps zero-scale code from 0V to 0.1 VREF
and full-scale code from VREF to 0.9 VREF. For a typical
reference voltage of 5V, the full-scale input range is now
0.5V to 4.5V, which provides adequate headroom for
powering the driving amplifier from a single 5.5V supply.
