The LTC
The LTC2328-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, it features a +10.24V true bipolar input range, making it ideal for high voltage applications requiring a wide dynamic range. The device achieves a maximum Integral Non-Linearity (INL) of +1.5LSB and guarantees no missing codes at 16 bits with a typical Signal-to-Noise Ratio (SNR) of 93.5dB.
Key features include an onboard single-shot capable reference buffer with a low drift 2.048V temperature compensated reference, and a high speed SPI-compatible serial interface supporting 1.8V to 5V logic levels. The LTC2328-16 offers a 1Msps throughput rate with no cycle latency and an internal conversion clock to ease external timing considerations. It dissipates only 50mW typical power and includes a sleep mode to reduce power consumption to 300µW during inactive periods.
