Operating from a single 5V supply, the LTC2337-18 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2337-18 achieves ±4LSB INL maximum, no missing codes at 18-bits with 100dB SNR. The LTC2337-18 has an onboard single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2337-18 also has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic wh...
