DESCRIPTION
18-Bit, 500ksps, Low Power
SAR ADC with 102dB SNR
The LTC2377-18 is a low noise, low power, high speed
18-bit successive approximation register (SAR) ADC.
Operating from a 2.5V supply, the LTC2377-18 has a
±VREF fully differential input range with VREF ranging from
2.5V to 5.1V. The LTC2377-18 consumes only 6.8mW and
achieves ±1.75LSB INL maximum, no missing codes at
18 bits with 102dB SNR.
The LTC2377-18 has a high speed SPI-compatible se-
rial interface that supports 1.8V, 2.5V, 3.3V and 5V logic
while also featuring a daisy-chain mode. The fast 500ksps
throughput with no cycle latency makes the LTC2377-18
ideally suited for a wide variety of high speed applications.
An internal oscillator sets the conversion time, easing exter-
nal timing considerations. The LTC2377-18 automatically
powers down between conversions, leading to reduced
power dissipation that scales with the sampling rate.
The LTC2377-18 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.
