Frequently Asked Questions
How many analog input channels does the LM12H458CIV support?
The LM12H458CIV supports 8 multiplexed analog input channels with 12-bit resolution. An internal sample-and-hold amplifier is integrated, so no external SHA is needed. This makes it suitable for multi-sensor data acquisition systems where multiple signals must be digitized sequentially.
Which package and temperature grade does the LM12H458CIV use?
The LM12H458CIV comes in a 48-pin CDIP (Ceramic Dual In-line Package) and is rated for the industrial temperature range of -40°C to +85°C. The ceramic package provides superior thermal and mechanical reliability compared to plastic alternatives, making it a common choice for industrial and defense-adjacent applications.
What supply voltage is required for the LM12H458CIV?
The LM12H458CIV operates from dual ±5V supplies. Both positive and negative rails are required to support the full-range bipolar analog input. Ensure your power subsystem can supply stable ±5V before using this device in a new design.
Are there drop-in alternatives for the LM12H458CIV?
The LM12458CIV (commercial-temp version) and LM12H458CIVX (tape-and-reel variant) are functionally equivalent alternatives within the same TI LM12 family. For broader alternatives, the ADS7846 or MAX197 offer similar multi-channel 12-bit ADC functionality in more modern packages with 3.3V compatibility.
Can I buy the LM12H458CIV in small quantities?
Yes. The LM12H458CIV is available with a minimum order quantity of 1 piece. The reference price starts at $17.49 per unit for single quantities and drops to $15.23 at 10,000-unit quantities. Inquire through FindMyChip for stock availability and lead time.
