Description

The LTC®2378-20 is a low noise, low power, high speed 20-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2378-20 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2378-20 consumes only 21mW and achieves ±2ppm INL maximum, no missing codes at 20 bits with 104dB SNR.

The LTC2378-20 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 1Msps throughput with no cycle latency makes the LTC2378-20 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2378-20 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.

The LTC2378-20 features a unique digital gain compression (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.

NOTES
  Setup:
   Set the terminal baud rate to 115200 and select the newline terminator.
   Equipment required is a precision voltage source (null box) and a precision voltmeter (to monitor voltage source).
   No external power supply is required.
   Ensure JP1 is installed in the default position from the factory.

  How to test:
   The voltage source should be connected with positive and negative leads to the positive & negative ADC inputs. Ensure the differential voltage is within the
   range of -VREF to +VREF. Swapping input voltages results in a reversed polarity reading.

@verbatim

The following parts (DUT) are pin-compatible, 20-bit A/D converters with serial I/O, and an internal reference:
LTC2376-20: 20-Bit, 250Ksps ADC
LTC2377-20: 20-Bit, 500Ksps ADC
LTC2378-20: 20-Bit, 1Msps ADC

The DUTs typically draw only 8.4 mA from a single 2.5V supply. The automatic nap and sleep modes benefit power sensitive applications. 

The DUTs DC performance is outstanding with a +/-0.5 ppm INL specification and 
no missing codes over temperature. The signal-to-noise ratio (SNR) for the LTC2378 is typically 104 dB, with the internal reference.  

Example Code:

Read ADC input.

    LTC2378_read(LTC2378_CS, &adc_code);   // Throws out last reading
    LTC2378_read(LTC2378_CS, &adc_code);   // Obtains the current reading and stores to adc_code variable

    // Convert adc_code to voltage
    adc_voltage = LTC2378_code_to_voltage(adc_code, vref);
