AD7667 datasheet

Description :

The AD7667 is a 16-bit, 1 MSPS, charge redistribution SAR analog-to-digital converter that operates from a single 5 V power supply. The part contains a high speed 16-bit sampling
ADC, an internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous applications, and a reduced power mode (Impulse) for low power applications where power is scaled with the throughput. The device is hardware factory-calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) in addition to the more traditional dc parameters of gain, offset, and linearity. Operation is specified from –40°C to +85°C.

Features

1. 2.5 V internal reference: typical drift 3 ppm/°C
2. Guaranteed max drift 15 ppm/°C
3. Throughput:
1 MSPS (Warp mode)

666 kSPS (Impulse mode)
4. INL: ±2.0 LSB max (±0.0038% of full scale)
5. 16-bit resolution with no missing codes
6. S/(N+D): 88 dB min @ 20 kHz
7. THD: –96 dB max @ 20 kHz
8. Analog input voltage range: 0 V to 2.5 V
9. Parallel and serial 5 V/3 V interface
10. Single 5 V supply operation
11. Pin-to-pin compatible with AD7671, AD7677
