The TC7106A and TC7107A are 3-1/2 digit direct-display drive analog-to-digital converters that allow existing 7106/7107 based systems to be upgraded. Each device has a precision reference with a 20ppm/°C max temperature coefficient. This represents a 4 to 7 times improvement over similar 3-1/2 digit converters. Existing 7106 and 7107 based systems may be upgraded.
The TC7106/TC7106A and TC7107/TC7107A are 3‑1/2‑digit dual‑slope integrating analog‑to‑digital converters. They provide direct‑drive LCD (TC7106) or LED (TC7107) displays, low‑noise operation, auto‑zero capability and high‑impedance differential inputs for precise measurements.
