The LM12458CIV from Texas Instruments is a highly integrated 12-bit + sign data acquisition system. It operates on a single 3V to 5.5V supply and combines a self-calibrating analog-to-digital converter (ADC) with a sample-and-hold circuit. This device features an 8-channel multiplexer and can store up to 32 consecutive conversions in an internal FIFO buffer.
Key electrical specifications include a 13-bit conversion time of 8.8 µs maximum and a throughput rate of up to 140k samples/s. It supports both single-ended and differential inputs, with an input voltage range from GND to VA+. The system includes a built-in 2.5V bandgap reference and can operate in a supervisory "watchdog" mode.
Packaged in a 44-LCC (J-Lead) format, the LM12458CIV is designed for surface mounting. It operates across a temperature range of -40°C to 85°C. The device features a parallel data interface and is suitable for applications in data logging, instrumentation, process control, and energy management.
The LM12458CIV offers a 12-bit + sign resolution.
The maximum sampling rate is 140kSPS.
The operating voltage range is 3V to 5.5V.
The operating temperature range is -40°C to 85°C.
The LM12458CIV is supplied in a 44-LCC (J-Lead) package for surface mounting.
