Linear Technology LTC2338IMS-18#PBF
- Part Number:
- LTC2338IMS-18#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3009783-LTC2338IMS-18#PBF
- Description:
- IC ADC 18BIT 1MSPS 16-MSOP
- Datasheet:
- LTC2338IMS-18#PBF
Description
The LTC2338-18 is an 18-bit, 1Msps, ±10.24V true bipolar, fully differential input ADC with 100dB SNR. It operates from a single 5V supply and has a ±4LSB INL (Max) and guaranteed 18-bit no missing codes. The LTC2338-18 has an onboard single-shot capable reference buffer and low drift (20ppm/°C Max) 2.048V internal reference. It also 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 1 Msps throughput with no cycle latency makes the LTC2338-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2338-18 dissipates only 50mW (Typ) and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the LTC2338-18 to 300μW for further power savings during inactive periods.
